Dr. James Leffew Retires D

r. James Leffew retired after teaching his final course this past summer. Dr. Leffew received his BSEE and MSEE from Purdue University in 1967. In 1985, he completed his PhD in Electrical Engineering at the University of South Florida. Prior to starting his teaching career at USF, Dr. Leffew was a member of the United States Navy, where he served as an Assistant Technical Director, Staff Weapons Officer, Engineering Test Pilot, Assistant Aircraft Maintenance Officer/Operational Test and Evaluation Pilot, and a Weapons Training Officer/Operational Squadron Pilot. Once at USF, Dr. Leffew quickly became an integral part of the undergraduate instructional faculty. Having taught almost every undergraduate course in the Electrical Engineering curriculum, Dr. Leffew has specialized in teaching digital and analog design and co-developed courses in VHDL and Rapid System Prototyping. His research focused on the areas of remote learning, remote laboratories, and remote control of industrial control systems over the internet. Students, staff and faculty alike were entertained with Dr. Leffew’s exciting stories of his time in the Navy as a test pilot and his experiences gleaned from both traveling the world, raising a family and teaching at USF for almost 40 years.

Students in EE continually recognize the worth of Dr. Leffew’s instruction during their time at USF: “Top notch professor. Class of 96’. 20 years later I can still go to a white board with nothing more than a marker and derive any logic problem to the amazement of my peers.” “Great professor…When you get an A in his course, best believe you earned it. Dr. Leffew can teach any class in the EE department and always willing to help with any course whether he is teaching it or not.” “One of the best people…(in) all my years of studying, I have never learned in 1 class the amount of things I learned in 4 years of college is less than what I learned in 1 semester with Dr. Leffew”

“Looking back on the 20 years since graduating, Dr. Leffew was by far the best professor I have ever had. He teaches realworld; expect nothing less from a Navy test pilot. Some of his statements have stayed with me over the years. He’s very hard, accepts nothing less than the best, and if you want to make it in life, take all of his classes.” “Dr Leffew is a walking computer where his textbooks are on his brain and his marker is the only way that he can show you the path to success.” “Dr. Leffew was one of the best professors I had at USF…This guy can walk in with his Coke can and marker and teach any course at any point.”

Dr. Leffew is looking forward to spending time with his wife, children and grandchildren while helping neighbors in his community that don’t have loved ones nearby. The irreplaceable knowledge imparted by Dr. Leffew to thousands of students will always be a part of our department.

(digital subscriber line), invention of multicode CDMA (used in 3G wireless), and pioneering the use of smart antennas (“MIMO�) for wireless systems. Earlier in his career, Gitlin led the team that created the first V.32/V.34 duplex, high-speed modems that used echo cancellation, fractionally spaced equalization, and trellis coded modulation. Since joining USF in 2008, Gitlin research has focused on the intersection of wireless communications and networking with biomedical engineering. He created an interdisciplinary team that is focused on wireless networking in vivo miniature wirelessly controlled

devices to advance minimally invasive surgery and other cyberphysical health care systems, such as a compact vectorcardiogram that provides 24x7 wireless connectivity of diagnostic-quality cardiac information. Gitlin is also exploring technologies for wireless 5G and Internet of Things (IoT) systems. Dr. Gitlin has graduated 7 PhD students and 2 MSEE students during his time at USF, and advised countless other students through both mentoring and instruction in his courses including Digital Communication Systems and Wireless Networks. His students


speak highly of him, PhD Graduate Mohamed Elkourdi praised Dr. Gitlin’s support: “I would consider myself fortunate to have had the opportunity to work and learn from my mentor, Dr. Gitlin, while obtaining my PhD. Something that always stood out to me was Dr. Gitlin’s commitment in helping his students succeed. During my work with Dr. Gitlin, we published many scientific papers, won a best paper award and were issued what has become my first U.S. patent, none of which would have been possible without his mentorship. Not only did Dr. Gitlin help me learn and grow professionally, but personally as well. He taught his students by sharing stories about his extensive experience in preforming and leading pioneering research in digital communication and wireless systems during his thirty two years at Bell Labs/Lucent Technologies. Within each story he shared was a lesson. Additionally, he was always a great source of inspiration, support, and guidance. Amazingly, his care and interest did not stop after graduation; he continues to stay in contact with his graduates to ensure that they continue to succeed, find careers, and excel in them” Doctoral Candidate Faeik Al Rabee discusses his experience with Dr. Gitlin:

“Prof. Richard D. Gitlin has been my supervisor in the Electrical Engineering graduate program at University of South Florida (USF) for 3.5 years. The first communication with Prof. Gitlin was in September 2015, through Skype, right before I came to the US to start my Ph.D. program in Electrical Engineering Department in Spring 2016. Prof. Gitlin is very accommodating and supporting. We started planning for my research during my first semester at USF, right after he helped me set my courses of study for the full period of my program. Throughout the program from setting my plan, conducting my research, writing and submitting research papers, improving my presentation skills, preparing for Doctoral Qualifying (DQE) and Candidacy Exams and writing my dissertation, Prof. Gitlin spared no effort to provide me with guidance and support every step of the way. Really, I would say that these years of working under his supervision have been one of the best academic years for me. He taught me a lot. Prof. Gitlin is open-minded, highly educated and is very aware of cultural diversity, which made my interaction with him so easy. He understood my cultural background and made my transition to American life an easy and The SOURCE

enjoyable experience. What I have learned while working with Prof. Gitlin will help me for the rest of my life. I am grateful and very lucky that I had such a pleasure and opportunity to work with him. He was a role model to me, and I will do my best to apply what I learned from him when I go back to my country, Jordan. I will always remember his motto “Work hard, play hard, dream big.”. It kept me motived and inspired me every step of the way. I understand that he decided to retire, but I am sure that his retirement does not mean the end of his active work. He will not stop here since he still has a lot to offer to the wireless communications field through his distinguished experience.

supervisor; it is much appreciated, and I shall miss working with you. Wishing you and your family all the best as you enter a new phase of your life. May you enjoy the extra time that you’ll be spending with them, may your future dreams come true, and may your life be filled with joy and happiness. Happy retirement!” After retiring, Dr. Gitlin plans to settle in California with his wife, children and grandchildren while still contributing to the field through patent consulting and as a courtesy faculty member in the Institute for Advanced Discovery & Innovation.

AGEP Florida Alliance Model project. The Alliance team is developing, implementing, studying, evaluating, disseminating and sustaining an AGEP Alliance Model to successfully advance STEM faculty career outcomes for historically underrepresented minority (URM) women doctoral students, postdoctoral researchers and early-career faculty. The project focuses interventions on professional development training via research boot camp experiences, mentoring and coaching by tenured women STEM faculty, and accessing support networks and programs through the National Center for Faculty Development and Diversity. Additionally, the Alliance team is engaging campus administrators and leadership to address systemic institutional barriers that are limiting the success of URM women in STEM faculty careers. The targeted outcomes of this AGEP Florida Alliance project include a large group of URM women publishing scholarly work in their STEM disciplines, securing faculty positions and earning tenure. The project's vision is to see the collaborative work sustained at the partnering universities and to see other institutions in our country adapt, adopt and reproduce this AGEP Alliance Model.

As the nation addresses a STEM achievement gap between URM and non-URM undergraduate and graduate students, our universities and colleges struggle to recruit, retain and promote URM STEM faculty who serve as role models and academic leaders for students to learn from, work with and emulate. Recent NSF reports indicate that URM STEM associate and full professors occupy only 8% of senior faculty positions at all four-year colleges and universities, and only about 6% of those positions at the nation's most researchintensive institutions. The AGEP Florida Alliance has the potential to advance a model to improve the success of female URM doctoral students and postdoctoral researchers as they enter STEM faculty careers, and to advance URM women early-career STEM faculty through tenure and promotion. Advancing the careers of URM women faculty ultimately leads to improved academic mentorship for undergraduate and graduate students in STEM fields. The integrated education research being conducted by this AGEP Alliance team investigates the underlying personal, interpersonal, organizational and professional issues and experiences that facilitate or


inhibit URM women STEM faculty career entrance, persistence and advancement. The research team is also investigating ways that URM women in STEM build skills, knowledge and competencies to successfully enter and persist in faculty careers. There is a Research Advisory Board that provides feedback to the AGEP Florida Alliance research team. The AGEP Florida Alliance Model institutions are working with an independent external evaluator who is conducting formative and summative evaluations. This AGEP Alliance also engages two advisory boards - an AGEP Florida Alliance Model External Advisory Board and an institutional Executive Leadership Board - that provide feedback to the institutions and the project team, and that suggest adjustments to project management about model development, implementation, testing, evaluation, dissemination, sustainability and reproduction potential. The institutional Executive Leadership Board is also addressing the institutional barriers that warrant change to successfully advance women URM STEM students, postdoctoral researchers and early-career faculty in

their transitions into and through faculty professions. The project team is disseminating findings from their research, and from their work on the AGEP Florida Alliance Model's development, implementation, selfstudy, evaluation, dissemination, sustainability and reproduction potential, by presenting at national conferences of STEM professional societies and publishing peer-reviewed articles in professional journals. Additionally, Dr. Sylvia Thomas had the opportunity to be a Guest Editor for a Special Issue of the Journal of Functional Biomaterials on the topic of "Conductive Polymers and Composites for Medical Application". This Special Issue aims at describing the recent progress in the design and investigation of functional conductive polymers and composite materials as smart devices to be applied in, but not limited to, biomaterials, bioengineering and bioelectronics.

USF Biomedical Engineering Pre-College Program In 2013 Dr. Saddow and Dr. Hoff, started the USF Biomedical Engineering Pre-College Program as a small portion of a one-day presentation organized by the College of Engineering. The popularity of the interactive nature of the program lead to the development of a stand-alone workshop for students interested in Biomedical Engineering. Over the years, the program has evolved from a one-day experience, to two 1-week programs offered in June and July. The program added many hands-on training elements, as well as cutting edge research lab tours in an effort to not only give students a taste of what Biomedical Engineering is about, but also develop practical skills that they could use no matter where they ended up. The additional cooperation of the Innovative Education department has served to bolster the program’s effective reach. The program has grown year-by-year, going from 27 applicants over 4 days in 2017, to 84 applicants over 5 days in 2019. With the increasing relevance of Biomedical Engineering in our day to day lives, and the support of the students and faculty of the USF College of Engineering and Department of Innovative Education, the USF Biomedical Engineering Pre-College Program is truly UnstoppaBULL.

ngineers at the University of South Florida have developed a new type of cybersecurity software that mimics the human immune system. It’s a concept that’s beginning to be explored more and more by researchers in a variety of fields: What does the human body do well and how can we adapt those mechanisms to improve technology or engineering systems? Researchers in the USF Department of Electrical Engineering looked to the human immune system as a model for intrusion detection in wireless sensor networks. The concepts apply equally well to highvalue financial or military mission critical networks that may or may not be wireless. The research was published in Procedia Computer Science and has demonstrated extremely promising results in testing. “It’s very logical to develop these software systems based on human

systems,” said Salvatore Morgera, PhD, a USF professor of electrical engineering and the project’s principal investigator. “Our immune system does a very good job at protecting us – so we wanted to take those mechanisms and adapt them

for cybersecurity.” To develop the software, Morgera, along with USF doctoral students Vishwa Alaparthy and Amar Amouri, broke the immune system down into three layers. The first layer is external protection; how our bodies prevent pathogens from getting inside. In their software, this layer

of protection is encryption – a common cybersecurity tool used to keep unauthorized users out of networks. Most network security methods depend almost exclusively on encryption, and while modern encryption techniques are extremely sophisticated, they are not always successful at preventing intrusion. To combat this risk, researchers looked to the bodies second layer of protection; non-specific resistance. This non-specific immune response acts as a “catch-all”, immediately responding to any foreign-body with a variety of non-specific immune cells. In their software, Morgera and his team developed a similar non-specific response that quickly recognizes any intrusion and quarantines the threat for further examination. Just like in the human body, this response acts as a first line of defense when threats enter the system. The third layer that researchers looked at is the immune system’s specific resistance to pathogens. This subsystem of the overall immune

system is composed of highly specialized cells that respond to specific pathogens. This response also builds immunological memory, leading to an enhanced response after the initial encounter. Just like in our bodies, the USF-developed software learns from each attack and maintains millions of intrusionfighting templates it can sort through to fight individual threat attempts. As Morgera states, “The need to sort through millions of intrusion-fighting templates can be a computationally complex undertaking.” Another researcher,

Patrick Lie Chin Cheong, and Morgera have developed a highly efficient ‘big data’ approach to the sorting that only takes fractions of a second and can be easily implemented on power-limited sensor networks using small microprocessors. When used in combination, these three mechanisms not only work to keep our bodies healthy but have been shown to be extremely successful in maintaining secure, high value digital networks.

Morgera and his team originally began this research as a potential new tool to secure wireless sensor networks deployed by the military. They have worked in collaboration with U.S. Special Operations Command (SOCOM) to test the software and have seen very promising results. Now, researchers plan to continue to improve the software and make it available for a variety of applications. It’s work that may change the future of cybersecurity around the world.

Dr. Ghani Receives NSF Grant to Develop Data-Driven Methodologies to Help Improve Security Methodologies for the Internet of Things (IoT)

A

multidisciplinary team of researchers from the University of South Florida, Florida Atlantic University, and the University of South Carolina, including Dr. Nasir Ghani (Professor of Electrical Engineering and Research Liaison at Cyber Florida) has received a research grant from the National Science Foundation (NSF) Office of Advanced Cyberinfrastructure (OAC). This project aims to develop novel methods to identify and remediate infected Internet of Things (IoT) devices in near realtime. Broadly, the IoT represents a range of networked sensors for collecting and transmitting data for specialized application needs. These technologies are rapidly proliferating across many diverse sectors (such as healthcare, finance, transportation, defense, and utilities), and studies project over 20 billion connected IoT devices within 5 years. However, IoT developers have largely focused on cost efficiency concerns and not given

adequate consideration to security needs. Given the smaller scale of IoT devices, this represents a major vulnerability due to the sensitive and critical nature of most collected data.

Indeed, many notable IoT-based cybersecurity incidents have already occurred, e.g., Mirai botnet and variants. Hence the team will analyze over 100 gigabyte/hour of real-time unsolicited Internet-scale traffic to develop efficient deep learning

classifiers to fingerprint IoT devices. Scalable offensive security algorithms will then be investigated, leveraging empirical Internet-wide data to build macroscopic remediation strategies. The evolution of IoT botnet infrastructures will also be analyzed using advanced graph theoretic algorithms. Finally, an operational IoT cybersecurity capability will also be established through a large online repository for sharing device data and threat information. Overall, this project is of 3 years duration and has received $500,000 in funding support from the NSF OAC Advanced Cyberinfrastructure Core program. Of this amount, approximately $100,000 will go to USF to lead the development of graph-theoretic models to uncover and characterize inter-related components forming malicious IoT cyberinfrastructures. All of the partners will also collaborate on setting up the operational IoT repository facility. The overall research team consists of Dr. Elias

Alumnus Creates Three Fellowships for PhD Students U

niversity of South Florida Electrical Engineering alumnus Krishna Barri, ‘03, is sharing his multimillion-dollar lottery winnings with the College of Engineering to help financially support students there. Barri, the winner of $14.5 million in a December 2018 Lotto drawing, is pitching in with a $500,000 gift to create three fellowships for PhD students in the college’s Department of Electrical Engineering where he earned his master’s degree. Barri says the large philanthropic gift is payback for the support he received when he began his graduate studies in 2000. Most importantly, according to Barri, that help included work as a research assistant to Professor Chris Ferekides, who is now the interim chair of the Electrical Engineering Department.

While Barri has accomplished considerable professional success, it wasn’t his original plan. He intended to pursue his PhD to conduct research and teach, but the need to earn a living took precedence, so his academic dreams were put on hold. The fellowships are named in honor of Barri’s parents Nageswara Rao and Tulasi Barri, and his brother-in-law Raghavendra Rao Palepu, all of whom he credits for his success. Originally from Visakhapatnam, India, Barri also gave $500,000 to support students in his home country.

After earning his master’s degree in electrical engineering, Barri found communication systems work with Verizon. He then co-founded W-B Solutions, an IT services and staffing company in Tampa, in 2012. His company has grown to employ more than 100 people.
