The Power of Finding, identifying, and evaluating online crowds for change

Dr. James Caverlee Social media—

user-generated content. Texas A&M computer scientist James Caverlee is studying the use of social media to harness collective intelligence to perform tasks, to persuade and change minds, and maybe even to change the world. As an expert in large-scale networked information systems—such as the World Wide Web, social media and mobile information systems—Caverlee looks at tremendous numbers of users and tremendous amounts of information, the places people go, the people they talk to and interact with, the content they are interested in, and the connections between them. These large-scale networked information systems are typically open and intentionally designed to encourage participation, Caverlee says. “This has lots of good benefits,” he says. “You see selforganized systems. You see serendipitous discovery of new information and new uses of these systems beyond what the systems designers had ever imagined. You see communities form. There are all these exciting possibilities that happen when you let people collaborate.” Now he wants to know whether these systems can be mined to find interesting or useful information to empower decision makers. Caverlee asks, can collective intelligence be harnessed?

Online gathering places

Crowds are naturally forming, Caverlee says, and the goal of his current research is to find these online crowds and engage them to accomplish tasks.

In 2010, Caverlee received a grant from the Defense Advanced Research Projects Agency (through the agency’s Information Innovation Office) to identify online “hotspots” in real-time social systems, mainly Twitter, where hundreds of millions of messages are posted per day. These online gatherings can be driven by natural disasters or by sporting events such as the Super Bowl. How do you find these hotspots in real time when huge numbers of people are posting hundreds of millions of messages? The task required developing algorithms and methods. After the Vancouver riots, people started posting photos and video and messages of the riots,” Caverlee says. “So you had this online reflection of current events. Assuming you can mine these large-scale systems and figure out where people are talking about this particular event, can we close the loop and engage with these crowds that are forming in these systems? “It’s a form of crowdsourcing,” Caverlee says. “Can crowds of people online work together intelligently, and if so, how?” Such crowdsourcing would be useful in a disaster, natural or otherwise. When disaster strikes, human impulse is for people on-site to use Facebook and Twitter to post photos and video of the damage, status updates, and their locations. Once these online crowds that have formed in response to this particular emergency are detected out of the hundreds of millions of other online activities, the challenge then becomes connecting the crowds to emergency responders. “If I am an emergency responder with limited resources, I need to know where to send trucks and rescue teams,” he says. “Emergency responders have to make these decisions


Annual Report 2011 - 2012 3

with limited information in the immediate moments after this disaster has struck. So let’s engage with these detected crowds and know where they are, but also issue them jobs to complete.” The National Science Foundation has sponsored some of Caverlee’s work in this area. He says that one job, for instance, would be for people to step outside their homes and take photos of the ground or buildings so that structural engineers can assess the safety of structures in the area. Computers can’t do that job, Caverlee says. Real people need to be directed to take better photos, to give better information that can help decision makers know where to send resources. “In the moment, as this is happening, the big challenge is to detect this crowd, connect them back to the stakeholder—in this case, the emergency responder—and then give them tasks to do to accelerate decision making and reduce response time.”

Crowd quality—in the moment

Alongside this detection and task assignment is assessing the relative quality of a newly formed crowd. A second project, this one funded by the National Science Foundation, aims to assess and monitor the quality of these crowds. A typical measure of Web quality is Google’s PageRank, or the content of a page or site, the number of clicks on a page, the links around the page, or how people engage with the site. CNN.com, for example, may be a reputable page compared with a blog because CNN has a lot of in-links, a long life on the Web, more site visitors and higher click rates. But crowds form in real-time systems in response to events, such as a presidential debate, a natural disaster or even just friends talking about a game. The crowd itself may not have a long life span, so a long history to assess the crowd

is not available. Instead, researchers have to develop other methods to evaluate relative quality. “We don’t have history for these people, or accounts,” Caverlee says, “so we have to make assessments in near real time and build models quickly so that we can speed and improve decision making.”

Spam: Not just potted meat

Caverlee says the flip side of these open systems is getting people to participate in, but not abuse, the system. “Spam has moved out of our e-mail inboxes and into these social systems,” he says, citing the example of Astroturf, a campaign that looks like a grassroots effort that instead uses fake accounts and bots to promote particular candidates or ideas. Caverlee started his research with Web spammers who tried to manipulate search engine rankings. But spam has evolved, and with the rise of social media such as Facebook, Twitter and Flickr, spammers are now infiltrating and attacking those systems. In work funded by Google and in collaboration with Steve Webb (then at Georgia Tech and now an independent consultant), Caverlee studied social spammers by deploying social honeypots, a new twist on a classic security reconnaissance trick to attract spammers and then study their tactics and behaviors to reverse engineer a solution to stop them. The research group ran the social honeypots in MySpace (when MySpace was still popular and active) and in Twitter, engaging in behaviors to attract spammers to them to serve as an early warning system to detect new and emerging behaviors in these social systems.

Caverlee looks at tremendous numbers of users and tremendous amounts of informaƟon, the places people go, the people they talk to and interact with, the content they are interested in, and the connecƟons between them.

In Twitter, the group set up accounts that didn’t tweet or tweeted only randomly, and that did not connect with other Twitter users. “These are passive accounts with no listed interests, that no active users would want to friend—these honeypots are irresistible to spammers,” Caverlee says. “So if one of these accounts tried to be friended, we would turn down the request but then crawl back to mine their profiles and connections. We could build machine-learned models of them based on artifacts of what they’ve left in the system.”

In this war of persuasion, then researchers want to know how to change people’s minds and views of the world. Typical spammer behavior is to follow as many other users as possible. Caverlee says an obvious sign of a bot-controlled account is a certain set ratio of friends to followers. Looking at user history showed that as soon as an upper threshold was reached, the bot-controlled account would immediately dump hundreds of followers to maintain the set ratio. Having many links per tweet is another red flag that a user is a bot-controlled account. With 60 Twitter honeypots, the team recorded 36,000 spammers in seven months. By modeling the behavior, the team could detect the spam accounts eight to 10 days before Twitter’s own spam detectors did.

Weapons of mass persuasion

The group noticed not only automated spam but also lots of coordinated spam, more like campaigns. The team found multiple accounts with similar talking points, and more subtle, sophisticated spam campaigns instead of brute-force spam that’s easier to identify. So the team’s current work, funded through U.S. Air Force Office of Scientific Research in spring 2012, is looking at propaganda and strategic manipulation in these large networked social systems. “The social Web and social media have essentially become a weapon of mass persuasion,” he says. “You have large numbers of people interacting with each other, so you see not only spam but political campaigns involved in this. You see evidence of governments and hate groups engaging in this.” In this war of persuasion, then, researchers want to know how to change people’s minds and views of the world. “We know that this is happening already, but we as researchers don’t have a very good handle on what’s going on, only anecdotal evidence,” he says. ArƟcle wriƩen by Lesley Kriewald

So Caverlee is now trying to detect persuasion at the scale of these large systems, finding these talking points and tracking their evolution. Coupled with that is building mathematical models that can explain this behavior. “Anecdotally, there’s this idea of tipping points, where things go viral,” he says. “Once we detect these campaigns, can we rewind the tape and build models? Can we find out if it’s the content of the message, or the topology of the social network, or is it key influencers or is it that the message reached a certain kind of inertia, a certain mass of people?” This all goes back to the idea of these open systems, Caverlee says. “Anyone can engage, anyone can promote their messages, so it all becomes a war of ideas. Because I’m a computer scientist, I’m trying to build computational methods for detecting and mining these campaigns, for modeling their evolution, for determining how to stop a campaign or determine the factors that make a campaign go global, and understanding the factors that influence all of this.” –fin

The world of social media is a crowded market: Facebook. Twitter. LinkedIn. Instagram. Pinterest. YouTube. Flickr. Google+. Foursquare.

Those are just the ones you’ve heard about, and the numbers are staggering: Facebook and Twitter combined have more than 1.5 billion users. If Facebook were a country, it would be the third largest, larger than the United States. Facebook gets more weekly traffic than Google, the largest search engine. YouTube is the secondlargest search engine.

In April 2012, Facebook paid $1 billion for mobile photo-sharing app Instagram.

Pinterest popularity has exploded from 400,000 unique users in May 2011 to 18.7 million in March 2012.

and on it goes.

Research Focus 5

Research focus:

The Brain Networks Laboratory The Brain Network Laboratory, founded by the late Prof. Bruce H. McCormick, designed and developed the Knife-Edge Scanning Microscope (KSEM), which enables whole-brain imaging of small animal brains at a sub-micrometer resolution. With the fine-grained anatomical data from the KESM, combined with innovative theoretical and computational investigations, the lab is working hard to reach its long-term goal of reverse engineering the brain. The image to the right is a 3D visualization of a Golgistained cell created using information gathered by the KESM.

Being self aware, humans have often wondered about how our brain works. We wonder about the mechanisms that facilitate thinking, cognition, and problem solving in addition to other functions of the brain. The concept of intelligence intrigues us; some scientists wonder if we can build artificial intelligences, but how would that work? How does our understanding of the biology of the brain relate to computing? Dr. Yoonsuck Choe, Associate Professor of Computer Science and Engineering, is tackling these questions head on in his Brain Networks Lab.

Dr. Yoonsuck Choe

“One of the major grand challenges in science and engineering in the 21st century is to reverse engineer the brain” says Dr. Choe. “I strongly believe that understanding the principles underlying brain function can revolutionize the way we think about computation and computers. This can lead to major breakthroughs in science and technology, much in the same way computers and the internet revolutionized our society at the end of the 20th century.”

His lab is taking a two-pronged approach in discovering how our brains function. The lab is aiming to recover and analyze the full circuit diagram of small animal brains by using the revolutionary Knife-Edge Scanning Microscope (KESM). The KESM, developed in the Brain Networks Lab, can cut very thin slices of small animal brain tissue and scan them at very high resolution, all in a fully automated system. The lab has been successful in imaging whole mouse brains and they are working hard to extract the rough connectivity information from the over 1.5 TB data per brain. The data is being used to construct an online atlas of the mouse brain to be used for research purposes.

“After we had designed and implemented the KESM instrument, we obtained full-brain data from multiple mouse brains. We are putting together a web-based brain atlas, the KESM Brain Atlas, which can be found at http://kesm.org, to allow public access to the full data that we have generated. We are also working on automated methods for geometric reconstruction of the objects such as neurons and blood vessels in our data sets so that a fully quantitative study can be done” says Choe. The second approach is theoretical. The brain has evolved with its main function being motor control. Higher cognitive functions such as memory and prediction all seem to serve this basic function. In this sense, time also becomes an important component, since memory and prediction can be viewed in terms of the past and the future. Motor actions unfold over time with its success dependent on precise timing. The Brain Networks Lab is looking into perceptual, temporal, and sensorimotor aspects of brain function at multiple levels to gain deeper insights into the core of brain function. Observing brain function at the synaptic level, single neuron level, map level, and the agent-environment level assists them in developing biologically inspired unsupervised and reinforcement learning algorithms to assist in their modeling and analysis. Ultimately, this research will allow scientists to build new technologies that will help humanity solve many problems and make the world a better, safer place to live. “Our research will lead to a deeper understanding of the principles underlying brain function and allow us to build tools based on these principles. These tools can have profound impact on science and technology. They can accelerate the rate of discovery of new scientific knowledge, help us explore broader and farther regions of space, help us treat mental disorders, and help us build assistive technology for the elderly and the physically impaired.” –fin


Faculty News, Awards, and Recognition 6

Stroustrup Honored with Festschrift Our University Distinguished Professor Bjarne Stroustrup, holder of the College of Engineering Chair in Computer Science, was honored with a festschrift held April 27-28, 2012. Dr. Stroustrup is the designer and original implementer of C++, one of the world’s most popular and most widely used programming languages. The Workshop on Quality Software: A Festschrift for Bjarne Stroustrup took place on the Texas A&M College Station campus in the newly dedicated Emerging Technologies Building. Guests and participants were able to engage in lively discussion via the many technical sessions and lectures, as well as enjoy themselves at the banquet held later in the evening of the event’s first day. In all, the festschrift was a fitting occasion to mark over thirty years of Dr. Stroustrup’s outstanding work in C++. The Workshop on Quality Software The Workshop on Quality Software was attended by a world-wide selection of Dr. Stroustrup’s colleagues. Among the many who participated were Dr. Ravi Sethi (president of Avaya Research, formerly AT&T), Dr. Lawrence Crowl (Google, formerly Sun), Dr. Alexander Stepanov (Amazon, formerly Adobe and SGI), Dr. Jan Christiaan van Winkel (Google, Zurich), Dr. Damian Dechev (Univ. of Central Florida), Dr. Hans Boehm (HewettPackard), Dr. Matt Austern (Google, formerly Apple), Dr. Vincent Lextrait (Chief Technical Officer of Amadeus), Alisdair Meredith (Bloomberg), Jonathan Caves (Microsoft), Dr. Peter Pirkelbauer (LLNL), Dr. Magne Haveraaen (University of Bergen), and Dr. Andrew Lumsdaine (Indiana University). Friends and former colleagues who could not attend sent messages, videos, photos, and congratulatory slides for display at a well-attended reception. The festschrift organizing committee consisted of faculty members Dr. Nancy Amato, Dr. Jaakko Järvi, Dr. Lawrence Rauchwerger, and Dr. Jennifer Welch. The event was sponsored by the Parasol Lab, the Texas A&M Department of Computer Science and Engineering, and the department’s Industrial Affiliates Program. The Festschrift provided the perfect ending to a busy and productive year for Dr. Stroustrup.

The Cambridge Connection:

In February, Dr. Stroustrup was honored to give the inaugural Wheeler Lecture at the University of Cambridge Computer Laboratory. There, he spoke about the style of C++11, which became an ISO standard this academic year, emphasizing its type-rich interfaces, compact data structures, integrated resource management and error handling, and highly-structured algorithmic code. Modern C++ is a language for programming based on light-weight abstraction with a direct and efficient

mapping to hardware, suitable for infrastructure code. Dr. Stroustrup began a life long association with Cambridge while working on his Ph.D. in computer science, which he received in 1979. In the summer of 2009, he gave a memorable lecture “Evolving a Language in and for the Real World” as part of the University’s 800th anniversary celebrations. Dr. Stroustrup is one of eight Overseas Fellows of Churchill College, a constituent college of the University of Cambridge and the national memorial to Sir Winston Churchill. The Wheeler Lecture is named after Dr. David Wheeler (1927-2004) who in 1951 received the world’s first Ph.D. in computer science from the University of Cambridge’s Computer Laboratory (then the Mathematical Laboratory). He was elected a fellow of the Royal Society in 1981 and in 2003 awarded Fellow of the Computer History Museum for his invention of the closed subroutine, his architectural contributions to the ILLIAC, the Cambridge Ring, and computer testing. Dr. Wheeler was Dr. Stroustrup’s thesis advisor at Cambridge.

A role in science and technology:

Also this past academic year, Dr. Stroustrup gave an invited lecture at CERN, The European Organization for Nuclear Research. C++ is the main programming language used for high-energy physics and for the design and operation of the world’s most powerful particle collider, the Large Hadron Collider. Dr. Stroustrup’s host “encouraged” him by pointing out that “Einstein stood here” and that most other physics greats had lectured from that spot. Later in the year, CERN was able to announce data that supports the existence of a new particle that is consistent with the elusive Higgs boson. Finding Higgs boson is of the major scientific achievements of our new millennium. A message of “Thanks!” from software teams at CERN on that day brought tears to his eyes. “I am very excited by the scientific and technological advances in which C++ has a role” says Stroustrup. “I lost hours of sleep to follow the landing of NASA’s new Mars Rover. I consider that a major technological triumph and am very proud that its critical autonomous driving and scene analysis software is written in C++.” Dr. Stroustrup is a highly esteemed researcher, inventor, and educator. Among his honors is his election to The National Academy of Engineering “for the creation of the C++ programming language.” As the first computer scientist ever, he was awarded the 2005 William Procter Prize for Scientific Achievement from Sigma Xi. He was given the IEEE Computer Society’s 2004 Computer Entrepreneur Award “for pioneering the development and commercialization of industrial-strength, object-oriented programming technologies, and the profound changes they fostered in business and industry.” He received the 1993 ACM Grace Murray Hopper award “for his early work laying the foundations for the C++ programming language.” Based on those foundations and Dr. Stroustrup’s continuing efforts, C++ has become “one of the most influential programming languages in the history of computing.”

Center for Emergency Informatics Established at Texas A&M

Dr. Robin Murphy, co-founder of the research fields rescue roboƟcs and human-robot interacƟon, tests one of her robots on a damaged structure at Disaster City. Dr. Murphy is the director of the newly-established Center for Emergency InformaƟcs at Texas A&M University.

The Board of Regents of the Texas A&M University System established the Texas Engineering Experiment Station’s (TEES) Center for Emergency Informatics (CEI) at its Aug. 3, 2012 meeting, recognizing the faculty effort in radically changing disaster response through advances in technology. Thirty faculty members in the Dwight Look College of Engineering at Texas A&M University have been working together since 2008 to create unmanned systems, new sensors, wireless networks, data mining, simulation and visualization, social networking, and other technologies that can revolutionize response and recovery. The center is unlike any other in the United States as it Dr. Robin Murphy focuses on how new and evolving information technologies can be improved, integrated, and put to use for disaster prevention, preparedness, response and recovery. “The time is now,” said CEI director Dr. Robin Murphy, Raytheon Professor in the Department of Computer Science

and Engineering at Texas A&M. “Texas needs the economic resilience to handle disasters, such as Hurricane Ike, which cost more than $22 billion to recover from. “The technology exists to get better information to the responders, cities and citizens. Information technologies are literally springing up overnight, with more than 1,000 new apps being created every day. And emergency informatics can create jobs; returning veterans, for instance, are already highly skilled and they need jobs.” CEI will serve to connect members of the Texas A&M family, including the Texas Engineering Extension Service (TEEX); Center for Robot-Assisted Search and Rescue; Hazards Reduction and Recovery Center; Institute for Science, Technology and Public Policy; Internet2 Technology Evaluation Center; and the RFID/Sensor Lab. The CEI will absorb the Emergency Informatics EDGE® Innovation Center, which is the nucleus for the 275-member industry consortium led by General Dynamics. Activities will commence with a seminar series throughout the academic year and a Summer Institute at TEEX’s Disaster City ® is being scheduled for May 2013.

The Montague-CTE Scholar program, named after its founding donor, Kenneth Montague '37, honors early-career excellence in undergraduate teaching at Texas A&M. Each year, the program recognizes one tenure-track assistant professor from each college who has demonstrated a commitment to excellence in undergraduate teaching. Montague-CTE Scholar awardees receive a $6,500 grant to encourage further development in his/her undergraduate teaching excellence. Caverlee's award is a result of an undergraduate teaching philosophy that is broad, but has recently focused on introducing students to massive data management and entrepreneurship. "Computer science naturally links theory to practice. Algorithmic advances in our discipline have directly spawned high-impact companies like Google and accelerated the growth of companies like Amazon and Facebook," says Dr. Caverlee. "The ability to make sense out of massive amounts of data, as well as the drive to create something new has helped these companies tremendously." In order to prepare his students to be technical and innovative leaders in large scale data management, he proposes to bring personalized cloud computing to his undergraduate classroom. "Cloud computing provides access to a scale of computing not possible in a traditional lab setting. Instead of data mining over smallish data that can fit on a single machine, my goal is for students to learn how to harness these massive computational resources for large-scale knowledge discovery. Students will learn how to setup and deploy cloud-based data analytics through Amazon Web Services, write MapReduce code for distributed data analysis, and build new mobile and social applications that utilize the cloud." Dr. Caverlee also continues to build on his efforts to encourage entrepreneurship among computer science and engineering undergraduates. "I'm excited about the opportunity of sparking a "startup culture" among our undergrads. I hope to encourage students to approach classroom projects and traditional learning modules as an opportunity for continued growth and turn them into practical, real-world applications that can have big impact."

To encourage this aim, Dr. Caverlee plans to use a portion of his Montague Scholar Award to invite local entrepreneurs and world-renowned experts to College Station to lead invited lectures, to coordinate "hackathons" (a hackathon is a loosely-organized programming environment that encourages creativity and collaboration), and meet with undergraduates in small group settings. "This is a tremendous honor … I am truly humbled. I'm especially thankful to the Montague family for this opportunity to enhance our undergraduate curriculum." In January 2012 Dr. Caverlee was one of 48 scientists and engineers who received grants from the Air Force Office of Scientific Research through its Young Investigator Research Program (YIP). He was selected for his research in detecting, analyzing, modeling, and predicting strategic manipulation and adversarial propaganda in social media. Dr. Caverlee and his research group will lead an integrated computational/socio-behavioral science effort to fundamentally advance both theories and systems for modeling mass persuasion in social media. The project will develop new algorithms for efficiently detecting evidence of existing persuasion campaigns in large-scale social media, build new models of social media-driven persuasion by drawing on recent advances in complexity science, and will analyze the spatial-temporal constraints of mass persuasion to identify new insights into the scope of persuasion and the factors impacting widespread adoption. The objective of the AFOSR-YIP program is to foster creative basic research in science and engineering, enhance early career development of outstanding young investigators, and increase opportunities for the young investigators to recognize the Air Force mission and the related challenges in science and engineering. Major research areas include aerospace, chemical and material sciences; physics and electronics; and mathematics, information and life sciences. The recipients selected will receive the grants over a 3 to 5 year period. Finally, in February, he was selected to receive the National Science Foundation Faculty Early CAREER award for his research into “Real-Time Crowd-Oriented Search and Computation Systems,” effective February 9, 2012. The award will fund a five year program with the goal of developing “the framework, algorithms, and systems for crowd-oriented search and computing, so that crowds discovered in emerging social systems may become part of in situ human-computational systems,” says Dr. Caverlee. Dr. Caverlee joined our department in 2007 after receiving his Ph.D. in Computer Science from the College of Computing at the Georgia Institute of Technology. During that time has also been awarded two Google research awards and a 2010 Defense Advanced Research Projects AgencyYoung Faculty Award.

Dos Reis and Schaefer win NSF CAREER Awards This past academic year we added three more faculty to our growing list of NSF CAREER awardees. Along with Dr. James Caverlee, whose CAREER grant is mentioned in the article on the previous page, Dr. Gabriel Dos Reis and Dr. Scott Schaefer were also recipients of this prestigious award. This brings the department total to nineteen CAREER awards. The NSF awards the CAREER grants to outstanding junior faculty members to help them advance their research and teaching activities. Dr. Gabriel Dos Reis received a grant for his continuing investigation of formal-methods-based principles and tools to make the practice of programming a more mathematical activity for ordinary programmers. Dr. Gabriel Dos Reis

Dr. ScoƩ Schaefer

His project, “Compilers for Dependable Computational Mathematics,” will be funded through May 2017. “The overriding aim is to make dependability a common, basic property of critical software. The results are expected to influence the evolution of existing major mainstream programming languages (such as C++) in their support for structured generic programming and improvement of software reliability,” says Dr. Dos Reis.

Our modern civilization has become extraordinarily dependent on software artifacts at virtually all levels of its structure. An immediate implication is that failures in software systems can cost human lives and are responsible for billions of dollars lost annually. Furthermore, silent failures of simulation software can seriously undermine the credibility of a scientific model, entailing profound intellectual liabilities. On the other hand, the algorithms we use in computational mathematics are becoming more and more complex. Yet, the programming languages we use to express them as computer programs do not seem to progress at a matching pace. As a result, there is an ever growing gap between the level of abstraction of published algorithms, and the software artifacts that realize them. In other words, the mapping between algorithms and code is no longer direct nor obvious, to the point where we have trouble convincing ourselves that our programs really do what they are supposed to do. Dr. Dos Reis’s research will investigate and develop tools to support research in axiomatic programming for computational mathematics. He will design new programming models rooted in a structured approach to generic programming. This project has the potential of an enabling technology in computational sciences, and the potential to change the way to think of programming and our approach to

software construction. Dr. Dos Reis will involve students both at the graduate and undergraduate levels, in hands-on, fully integrated research-based classes. Dr. Dos Reis received his Ph.D. in Mathematics from the University of Paris VII and École Normale Supérieure de Cachan—France in 2001. He worked as a Postdoctoral Research Associate for INRIA Sophia Antipolis in France and for our department before joining as faculty. His research interests include computer algebra, mathematical software, formal verification, programming languages, compiler construction, and generic programming. Dr. Dos Reis is presently a trustee of the Calculemus project; project lead of the OpenAxiom computer algebra system; project lead of the Liz programming system; member of the ISO C++ Standards Committee; and member of the AFNOR (French national body for standardizations) C++ committee. Dr. Scott Schaefer, an associate professor of computer science and engineering, received his CAREER award for research in graphics and visualization. Dr. Schaefer was non-tenured at the time he was selected for the award. Dr. Schaefer’s project, “Parameterization and Tessellation for Computer Graphics” will be funded through May 2017. “Project outcomes will significantly advance the state of the art not only in computer graphics and geometric modeling, but also in other areas of applied mathematics and computer science where the representation and precise control of smooth freeform shapes play a key role,” says Dr. Schaefer. Parameterization underlies nearly all curve and surface representations in Computer Graphics. Typically the effect of parameterization is ignored, yet this is a degree of freedom that can have a large effect on the shape of the curve. Parameterization is also used to tessellate surfaces on graphics cards, which is a process of taking high quality shapes such as those found in movies and turning the shapes into triangles for the graphics card to draw. The investigation of “the fundamental connection between parameterization and surface shape or quality for parametric curves, surfaces and volumes” leads Dr. Schaefer’s research. “He will expand upon the concept of non-uniform parameterization of surfaces and volumes. And he will design new representations that allow the user to control or automatically adapt the parameterization of these shapes during the design process, and incorporate methods of nonuniform parameterization that are currently not possible.” This work has potential applications in surface design in the automotive, aeronautics, and entertainment industries and even in finite element computations for physical simulations. Dr. Schaefer received his PhD in Computer Science from Rice University in 2006 and joined the Department of Computer Science and Engineering at Texas A&M University in the same year. His teaching and research interests include computer graphics, geometric modeling, and scientific visualization. Congratulations to all of our CAREER awardees!


Student News, Awards, and Recognition 12

Grad Student Jon Moeller awarded Best Paper Honorable Mention; featured in Best Buy Commercial

CSE graduate student Jon Moeller and the ZeroTouch device as seen in the Best Buy “Future Innovators” commercial. ZeroTouch has garnered interest from both the entertainment and compuƟng industries. Graduate student Jon Moeller and his advisor Dr. Andruid Kerne were awarded a Best Paper Honorable Mention by the prestigious ACM Computer Human Interaction (CHI 2012) conference for their paper "ZeroTouch: An Optical Multi-Touch and Free-Air Interaction Architecture." The ZeroTouch multi-touch and free-air interaction sensing technology has the potential to transform how people interact with televisions, automobiles, building energy systems, and other walks of life. Kerne’s research group, The Interface Ecology Lab, strives to build relationships, developing new methods connecting computing, engineering, social sciences, the arts, and other fields to human experience. Over the past year ZeroTouch has garnered much attention for its innovative nature and relatively cheap cost. Touchsensitive frames have enabled interactive surfaces for years, but the size and responsiveness tend to be limited. ZeroTouch, developed with support from the National Science Foundation, enables precise sensing within a specific plane of interaction. While watching the latest season of Mad Men, many of us in computer science and engineering were excited to see one of our own in a nationally aired commercial for Best Buy. However, it was no surprise that it was Jon Moeller and the ZeroTouch device that appeared in the commercial titled, "Future Innovators." "I had no idea that ZeroTouch would become such a big deal" says Moeller. "I was skeptical at first about doing the commercial, but now that I've seen what they put together,

I'm really happy how it turned out. The shoot day was pretty tiring. I have a new respect for actors after performing in the commercial." At ACM CHI 2012, the Interface Ecology Lab exhibit featured one ZeroTouch integrated with a 55" LCD, heralding a new era of responsive televisions. Also featured were three ZeroTouch sensors for eSports competition, two of them integrated with pen-based computing. Another pen + multi-touch sensor ran Embodied InfoComposer, a single display groupware for helping people curate connected and rich collections of visual bookmarks. Another application, Zooming Bookmarker used ZeroTouch to bring multi-touch into Google's Chrome browser. And finally, the free-air interaction of intangibleCanvas, reminiscent of technologies imagined in the movies Minority Report and Iron Man, invites attendees to collaborate in a painting space. ZeroTouch's popularity has opened the door for new collaborations between the Interface Ecology Lab and the entertainment industry. The future of the device is bright. "We are working to develop relationships with entertainment companies, such as ESPN, Disney, and Pixar, and computing device experience companies, such as Apple and Google, in order to bring ZeroTouch to the world," says Dr. Kerne. "In The Interface Ecology Lab, students and faculty collaborate to form and realize visions of transforming computing technology so that human experiences grow more expressive, creative, participatory, and fun. Our continuing work with ZeroTouch is a prime example. Research feeds education feeds research, in an eternal golden braid."

Texas A&M Wins First at Regional, Third at National Cyber Defense Competition maintain the business’s network, to respond to security and administrative tasks, and to defend against attacks. “A volunteer red team tries to compromise the network,” says Creager. “It looks around on the first morning of the competition to get a feel for the business’s network structure before beginning to hack the system.”

The Texas A&M University team won the 2012 Southwest Collegiate Cyber Defense Competition (SWCCDC) for the fourth time in a row. Second and third place went to teams from Oklahoma State University and the University of Texas at Austin, respectively. The 2012 SWCCDC was held March 10-12 at Texas Engineering Extension Service’s Disaster City in the Emergency Operations Training Center located in College Station. Texas A&M advanced to the national finals in San Antonio where they finished third place. The SWCCDC asked student teams to assume administrative and protective duties for a small business’s computer network comprised of multiple servers and Internet services such as a web server, mail server, and e-commerce site. “The student teams are hired to replace an incompetent group of system administrators,” says Gerry Creager, event organizer.

The color-coded teams are comprised of the blue team, the “hired” troubleshooting administrators; the white team, the executives and administrators of the small business; the gold team, the judges and senior staff; and the aforementioned red team, the hackers. Business hours are maintained during the competition starting at 8:30 a.m. on Saturday and ending at noon on Sunday. Congratulations to the Texas A&M team members: Nik Johnson, Ross Dixon, Ryan Schmidt, Taahir Ahmed, Robert Schumacher, Mark Browning, and Katelyn Seloff. Most of the team members are undergraduates from the Department of Computer Science and Engineering and the Department of Electrical and Computer Engineering. CCDC Events are designed to build a meaningful mechanism by which institutions of higher education may evaluate their programs, provide an educational venue in which students are able to apply the theory and practical skills they have learned in their course work, foster a spirit of teamwork, ethical behavior, and effective communication both within and across teams, and create interest and awareness among participating institutions and students.

Each team begins the competition with an identical set of hardware and software and is scored on its ability to

Suarez Awarded BTD Fellowship In the Fall of 2011, CSE graduate student Jesus Suarez received the Bridge to Doctorate (BTD) fellowship from the National Science Foundation, which is administered by the TAMUS LSAMP (Louis Stokes Alliance for Minority Participation) program. The BTD fellowship paid for his travel to attend the 2011 IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR) held November 1-5 in Kyoto, Japan, where he presented his research "A Survey of Animal Foraging for Directed, Persistent Search by Rescue Robotics." Additionally, the fellowship funds his graduate school study and research for two years. Currently, Jesus is in the PhD program in the Department of Computer Science and Engineering at Texas A&M University. When he began as an undergrad in Dr. Robin Murphy's lab last year, his research interest was centered on

autonomous search and navigation. Since then his focus has changed to computer vision for human robot interaction. "I'd like to improve the quality of interaction between people and robots by using gesture recognition to make the communication more natural for the person. My ultimate career goal is to become a professor," says Suarez. The Texas A&M University System LSAMP program goal is to increase the quality and quantity of underrepresented students successfully completing science, technology, engineering and mathematics (STEM) baccalaureate degree programs, and to boost the number of underrepresented students interested in programs of graduate study. The intent of this program is to link underrepresented undergraduate students with active and supportive faculty-researchers who will mentor them and provide them with opportunities to engage in research-related activities, as early as possible in the students' academic careers. Jesus' academic advisor is Dr. Robin Murphy, Raytheon Professor of Computer Science and Engineering and Director of the Center for Robot-Assisted Search and Rescue.

A&M Team Takes 2nd in ACM Regional Programming Contest On October 29, 2011 at Baylor University, Texas A&M University’s Maroon Team took 2nd place in the 2011 ACM South Central USA Regional Programming Contest, or what’s referred to as the Battle of the Brains. The competition consisted of 60 teams from universities covering Texas, Louisiana, and Oklahoma, all vying for a spot to attend International Collegiate Programming Contest World Finals that was held in Warsaw, Poland on May 14-18, 2012. “While the Battle of the Brains exposes students to IBM’s Smarter Planet Initiative, the contest itself embraces a global theme. Thirty years ago, the contest pulled from just a few countries. Today, contest participation has grown more than 800 percent, with teams from 90 countries on six continents participating in their individual Regional phases,” said Doug Heintzman, director of strategy at IBM Software Group and sponsorship executive of the ICPC. The Regional teams are given 8 problems and are ranked according to how many problems they can solve correctly, and then by the total amount of time taken to solve

the problems. Texas A&M’s Maroon team was one of three teams to answer 4 of the 8 problems, doing so in a total time faster than the other two teams. A team from the University of Tulsa finished first, solving 5 of the 8 problems, and a team from Rice University finished third. Texas A&M’s teams’ coach Dr. John Keyser said, “It was exciting to finish well, but a bit disappointing to be passed near the very end by the winning team. The Maroon team solved all four of its problems in the first 2 hours 45 minutes, during which time Tulsa solved only one. But, in that last 2 hours 15 minutes, Tulsa solved four more, moving into first place.” Team Aggies and Team White finished in 15th and 23rd places, respectively. Team Members for the Maroon Team were Kyle Willmon, senior in computer science, Ryan Schmidt, junior in computer science, and Robert Schumacher, senior in computer engineering. The ACM International Collegiate Programming Contest evolved from a competition held here at Texas A&M in 1970 hosted by the Alpha Chapter of the UPE Computer Science Honor Society.

CSE Research Experiences for Undergraduates (REU)

2012 CSE REU parƟcipants, mentors, and sponsors take a break from presenƟng posters to take a group photo. The poster sessions are an excellent opportunity for the REU students to present their work to the public as well as be rewarded for a summer’s worth of hard work. Summer 2012 marked the ninth year that the CSE department offered Research Experiences for Undergraduates (REU@ CSE). In addition to the REU program, the department offers the Dwight Look College of Engineering Undergraduate Summer Research Grants (USRG) program, the Computer Research Association’s Committee on the Status of Women in Computing Research (CRA-W) Distributed Mentor Project (DMP), and the CRA-W and Coalition to Diversify Computing Distributed REU (DREU). These summer research programs span the 10-week summer term and involve undergraduate students from Texas A&M and other colleges and universities from around the world. During the summer research experience, participants work closely with faculty members, graduate students and undergraduate mentors on current research projects, make short progress presentations to their peers during program meetings, attend presentation skills workshops, make a formal poster presentation of their research experience at the end of the program, create a personal website and submit a written, final report describing the results of their research. The goal is that the students participating in the CSE REU program will make significant contributions to ongoing faculty research and, more importantly, will gain an appreciation for and an interest in graduate school and a future research career.
