HONORING THE LIFE OF DR. PAUL GADER Paul Gader, Ph.D.

Dear Colleagues, It is with a heavy heart that I share with you that our colleague and friend, Dr. Paul Gader, passed away on Tuesday night surrounded by his loved ones.

Paul received his master’s and doctorate in mathematics from the University of Florida in 1983 and 1986, respectively. He served as a faculty member at UF since 2001, beginning as an associate professor in the Department of Computer & Information Science & Engineering (CISE) and later, in 2003, becoming a full professor. Paul served as chair of CISE from 2012 to 2015 and joined ESSIE as an affiliate professor in 2016. Paul was an internationally recognized expert in machine learning and algorithm development, initially working on land-mine detection and handwriting analysis and later expanding this work to study hyperspectral image analysis and a broad range of environmental issues. He published more than 300 total papers, served as an associate editor of IEEE Geoscience & Remote Sensing Letters, enjoyed a threeyear term as a UF Research Foundation Professor, and was elected a Fellow of the IEEE. These accolades tell only part of the story about why Paul was such an important influence on his students and colleagues, as well as the college. He was brilliant but humble, always willing to step up and help irrespective of the complexity of the situation or current demands on his time. Anyone who knew him will tell you that Paul was truly one of the best of us.

Paul, you will be greatly missed. We offer our condolences to his loved ones and to those of you who were close with him.

Kejun Huang, Ph.D.

HUANG TO USE CAREER AWARD TO TACKLE AI’S UNSUPERVISED LEARNING CHALLENGES Kejun Huang, Ph.D., an assistant professor, has received a CAREER award from the National Science Foundation (NSF). His project, “Principled Unsupervised Learning via Minimum Volume Polytopic Embedding,” will focus on machine learning that addresses the challenges of unsupervised learning, which teaches the machine, or an AI system, to understand patterns in data.

“If we want to develop a program to recognize whether there is a cat in an image, supervised learning requires that the algorithm is provided with a large set of images, and each of them is provided with the correct label of ‘cat’ or ‘no cat.’

This requirement may or may not be realistic in practice,” Dr. Huang said. “For unsupervised learning, the algorithm automatically finds patterns in the data without asking for specific examples of what the pattern is during the data preparation stage.”

There are two major challenges in unsupervised learning:

1) how do we know if the learned representation is correct, meaning it is mathematically the unique solution? 2) all the existing models are known to be computationally hard to solve, as no known algorithm is guaranteed to exactly solve the problem within polynomial-time, also known as “NP-hard.”

“The overarching goal of this project is to resolve all three of these issues by developing a principled framework of minimum volume polytopic embedding for unsupervised learning,” Dr. Huang said.

CAREER awards are NSF’s most prestigious award for junior faculty and are designed to help provide a foundation for a lifetime of scientific leadership.

The awards are given to an outstanding scientist who exemplifies the role of teacher-scholars through research, education, and the integration of education and research.

CRACKING THE CODE: BUILDING A DNA MAP FOR HUMAN CANCER DETECTION FROM OTHER SPECIES Kiley Graim, Ph.D., assistant professor, is leading a $1.5 million National Institutes of Health (NIH) National Cancer Institute study with co-investigator James Cahill, Ph.D., an assistant instructional professor in the Department of Environmental Engineering Sciences. Together with Ji-Hyun Lee, DrPH, a professor in the Department of Biostatistics, their grant seeks to create a panmammalian tumor atlas that will aid in the development of artificial intelligence (AI) tools to model the evolution of cancer across hundreds of mammalian species — and its correlation to humans.

As is always the case with creating reliable AI, it demands huge amounts of clinical data to become a viable tool. Particularly where the cancers are a rare variety, a sufficiency of samples is rarer still.

“We’re not getting enough people in clinical trials because their diseases are too rare, and people aren’t lining up as donors of healthy bone tissue,” Dr. Graim said. “That prevents us from getting traction from machine learning, which requires big data. We might only have a few hundred samples and a few billion base pairs in each of their genomes. Building a model from those leaves far too many variables; I have more genes that are going to change in each patient than I have patients.”

compare bone cancer in mice, dogs and humans,” Dr. Graim said. “They’re very closely related and we can look at the ancestral networks — how the genes interact with each other. It works really well.”

A NOVEL SEARCH FOR BIG DATA TO FEED MACHINE LEARNING Seeking a sufficient clinical data set, Dr. Graim recruited the evolutionary biology and comparative genomics expertise of Dr. Cahill, pulling in millions of years of evolution data to see the commonalities in various species that develop cancer and those that don’t.

“We’re looking at all cancers, but we’re trying to identify good model organisms for rare cancers, as the data set from which to draw those is so much smaller,” Dr. Cahill said. “We’re looking at a wide array of mammals, quantifying their relationship to each other in a complex way. The machine-learning models can leverage both close- and dissimilarly related species so there’s a hierarchy of the different parts of the genomes and how similar they are across all of those.”

She observed that dogs are 75 times more likely to get osteosarcoma than humans — and UF gets tons of cases coming through every year, yielding valuable data.

Studies have indicated that breast cancer in dogs and humans is very similar, with the same genome subtypes which respond to the same treatments. While most cancer research is done either on humans or mice, this NIH R01 grant, specific to early-stage investigators, is allowing the UF team to look at several hundred different species at the same time. Dr. Graim noted that this approach is better because of the number of samples it produces, and because they are closely related species for which their team has done a lot of work to understand the genomic difference between them.

HOW A HORSE WHISPERER CAN HELP ENGINEERS BUILD BETTER ROBOTS Humans and horses have enjoyed a strong working relationship for nearly 10,000 years — a partnership that transformed how food was produced, people were transported and even how wars were fought and won.

Can these age-old interactions between people and their horses teach us something about building robots designed to improve our lives? Researchers at the University of Florida say yes.

“There are no fundamental guiding principles for how to build an effective working relationship between robots and humans,” said Eakta Jain, Ph.D., an associate professor. “As we work to improve how humans interact with autonomous vehicles and other forms of AI, it occurred to me that we’ve done this before with horses. This relationship has existed for millennia but was never leveraged to provide insights for human-robot interaction.”

Dr. Jain conducted a year of fieldwork observing the special interactions among horses and humans at the UF Horse Teaching Unit in Gainesville, Fla. She recently presented her findings at the Association for Computing Machinery Conference on Human Factors in

Computing Systems in Hamburg, Germany.

As horses did thousands of years before, robots are entering our lives and workplaces as companions and teammates. They vacuum our floors, help educate and entertain our children, and studies are showing that social robots can be effective therapy tools to help improve mental and physical health. Increasingly, robots are found in factories and warehouses, working collaboratively with human workers and sometimes even called co-bots.

“Some of the findings are concrete and easy to visualize, while others are more abstract,” she says.

“For example, we learned that a horse speaks with its body. You can see its ears pointing to where something caught its attention. We could build in similar types of nonverbal expressions in our robots, like ears that point when there is a knock on the door or something visual in the car when there’s a pedestrian on that side of the street.”

LASER ATTACK BLINDS AUTONOMOUS VEHICLES, DELETING PEDESTRIANS AND CONFUSING CARS Self-driving cars, like the human drivers that preceded them, need to see what’s around them to avoid obstacles and drive safely.

The most sophisticated autonomous vehicles typically use lidar, a spinning radar-type device that acts as the eyes of the car. Lidar provides constant information about the distance to objects so the car can decide what actions are safe to take.

But these eyes, it turns out, can be tricked.

New research reveals that expertly timed lasers shined at an approaching lidar system can create a blind spot in front of the vehicle large enough to completely hide moving pedestrians and other obstacles. The deleted data causes the cars to think the road is safe to continue moving along, endangering whatever may be in the attack’s blind spot.

This is the first time that lidar sensors have been tricked into deleting data about obstacles.

The vulnerability was uncovered by researchers from the University of Florida,

the University of Michigan and the University of Electro-Communications in Japan. The scientists also provide upgrades that could eliminate this weakness to protect people from malicious attacks.

The findings will be presented at the 2023 USENIX Security Symposium and are publicly available online.

Lidar works by emitting laser light and capturing the reflections to calculate distances, much like how a bat’s echolocation uses sound echoes. The attack creates fake reflections to scramble the sensor.

“We mimic the lidar reflections with our laser to make the sensor discount other reflections that are coming in from genuine obstacles,” said Sara Rampazzi, Ph.D., a CISE assistant profesor who led the study. “The lidar is still receiving genuine data from the obstacle, but the data are automatically discarded because our fake reflections are the only ones perceived by the sensor.”

STUDENT AWARDS

STUDENT WINS BEST PAPER AWARD AT ACM CONFERENCE Aysegul Bumin, Ph.D., along with her team received the best student paper award at the 13th Association for Computing Machinery Conference on Bioinformatics, Computational Biology, and Ta m e r Ka hve ci, Ph . D. (l e f t), & Ayse g u l B u min, Ph . D. Health Informatics (ACM BCB) for her research on fiber-based tensor completion for drug repurposing.

The paper titled, “FiT : Fiber-based tensor completion for drug repurposing,” was coauthored by Anna Ritz, Ph.D., an associate professor in the Biology Department at Reed College; Donna Slonim, Ph.D., a professor in the Department of Computer Science at Tufts University; Tamer Kahveci, Ph.D., a CISE professor; and Kejun Huang, Ph.D., a CISE assistant professor. The research focuses on the problem of missing data in fiber structure, and

the method proposed provides fast and accurate imputations compared to existing algorithms. The imputed values are used for solving an important problem: drug repurposing.

Drug repurposing is the process of finding new uses for drugs or compounds already in development. Repurposing existing drugs for novel indications reduces drug development time and cost, and can decrease the risk of failure, as developing new drugs and compounds for different disease-affected cells with unique traits is costly and can take decades, making drug repurposing a necessity.

ACM-BCB is the premier conference covering all aspects of bioinformatics research, including design, analysis, specification, verification, implementation and performance.

CLEARING HURDLES: SHPE PROGRAM PROPELS FUTURE LEADERS IN ENGINEERING Society of Hispanic Professional Engineers (SHPE), including delegates from UF SHPE, was granted an unprecedented three-hour briefing on “Building the Next Generation of Hispanic Leaders in STEM” with officials at the White House. The discussion revolved around how academia, the private sector, and government can increase Hispanic representation in the tech ecosystem by lowering education and career barriers for Hispanic students and professional engineers.

“In line with our new strategic plan, this prestigious event is a significant step towards achieving our goal of being a key voice in Washington, D.C. with deep reach and a reputation as the leading organization for Hispanics in STEM,” said Miguel Alemañy, interim SHPE CEO. “The entire familia should be proud to see SHPE with a seat at this table.”

The briefing was organized into three conversations: K-12, Gender Equity, and Workforce Pathways. An underlying theme across the discourse was the involvement of the entire family in every student’s success, a role that SHPE fills in its mission by embracing and including family in a similar way that Hispanic culture centers family. While all students benefit from the support of family to be successful in a field as demanding as engineering, Hispanic students often face a complex web of barriers in their pursuit of STEM education, such as language barriers, immigration issues, and overcoming stereotypes. Navigating these obstacles requires a unique blend of resilience, creativity, and determination, which are qualities that bolster and galvanize all engineering professionals.

WICSE HOSTS CODE-A-THON FOR GAINESVILLE STUDENTS Women in Computer Science and Engineering (WiCSE), the official student Association for Computing Machinery’s Council on Women in Computing (ACM-W) chapter at the University of Florida, recently hosted its annual Middle and High School Code-A-Thon. The group welcomed about 35 Gainesville-area middle and high school students for a day of interactive and educational computer science workshops.

Students were split into two groups based on prior computer science knowledge. The more beginner group participated in workshops that introduced them to binary, hex, logic gates, and Arduinos while the more advanced group participated in data structures, introductory cybersecurity, neural networks, and React workshops.

The workshops were hosted by a variety of student organizations from UF, including Women in Electrical and Computer Engineering (WECE), the

UF Student Information Security Team (UFSIT), the UF Programming Team (UFPT), the UF Software Engineering Club (UFSEC), and Dream Team Engineering.

“Computer Science education is important for the future of our society,” said Rong Zhang, Ph.D., an instructional associate professor in the Department of Computer & Information Science & Engineering and co-advisor for WiCSE. “WiCSE and UF-TYPE are dedicated to introducing coding skills to students at an early age.”

WiCSE’s mission is to facilitate the growth and empowerment of women in computer science by educating and celebrating their participation in the field. The group holds professional development workshops, and social and outreach events. WiCSE welcomes any and all UF students to join. To learn more, visit https://ufwicse.com/.

UF INFORMATION SECURITY TEAM WINS COMPUTER SECURITY COMPETITION A group of students representing the UF Student InfoSec Team (UF-SIT) Kernel Sanders team recently won a Capture the Flag (CTF) tournament sponsored by Raymond James in St. Petersburg, Fla. By finishing first, the team won a $10,000 prize.

“Although different teams have been participating in this competition for a while, UF has often placed near the top,” said Joe Wilson, Ph.D., associate professor and the group’s faculty sponsor. “The competition has always been tough, and this win is special.”

The Kernel Sanders team was founded in the Fall of 2006 by Jordan Wiens and John Sawyer, who were both working in UF Information Security at the time. Team members for this event include Scott Lagler (captain), Miguel Caputo, Ayden Colby, Robert Dick and Jeffery Luo. The competition was a one-day event with the theme “The Watchers at the Wall,” a blue-teamthemed CTF managed by Warl0ckgam3z, an online testing and training challenge architecture for individual participants or teams. The “blue team” is comprised of people in an organization who work on defending their information security resources

from attack.

The challenges involved a variety of problems, from physical challenges such as lock picking and fitness (a rarity for CTFs), typical code cracking problems, extracting and decoding remote desktop sessions, and identifying and exploiting operating system misconfiguration, among others.

Several teams were clustered near the top of the scoreboard just before the end of the competition, but UF team’s points from ancillary challenges such as Hacker Jeopardy, lock picking, physical fitness, and Lego building put them over the top.

There are no club dues or applications required to join UF-SIT. The group generally does around 5060 competitions each year, varying in scale and duration, with most contests online. UF-SIT funding comes from student government, and the group welcomes the support of sponsors to help fund student travel to these types of competitions.

Visit the UF-SIT or join their slack channel to learn more about the group and how to become a member.
