Researcher Spotlight: CAR-STOP’s Joydeep Ghosh and Robert Heath, Jr.
Written by Lauren Bringle
Profs. Robert W. Heath, Jr. and Joydeep Ghosh are powerhouses on the international stage of top engineering faculty and researchers. With a combined 44 years of experience at The University of Texas at Austin between them, the two researchers are still producing groundbreaking developments on a regular basis.
Their current TxDOT project, the Communications and Radar-Supported Transportation Operations and Planning (CAR-STOP), is designed to set a new standard for the automated vehicle industry. The project brings together Robert Heath’s expertise in wireless networking and communications, Joydeep Ghosh’s expertise in data science, and CTR Director Chandra Bhat’s expertise in travel modeling and simulation. Always seeking to advance the transportation field through interdisciplinary work, CTR was pleased to anchor a major innovative project with researchers from the Department of Electrical and Computer Engineering.
Over 80 percent of annual car crashes could be prevented by vehicular communications, a recent NHTSA report demonstrates. As Bhat, the principal investigator of the CAR-STOP project, observes, “This exciting interdisciplinary project was initiated to improve vehicular communications and substantially improve safety benefits for drivers, cyclists, pedestrians and any other transportation users.” The project will create a new framework to integrate radar sensing and vehicle-to-vehicle communications to improve safety for partially automated vehicles. Additionally, the project will develop the means for vehicles to exchange higher rates of sensor data using millimeter wave communication.
The two professors recently founded another major research initiative, known as the Situation-Aware Vehicular Engineering Systems (SAVES) project (another multidisciplinary collaboration), to explore the emerging interconnection between wireless and transportation. SAVES combines the fields of wireless networking and communications, data and signal processing, transportation, traffic modeling, policy and planning to help reduce collisions, design faster commutes, and increase connectivity to make the automated aspects of driving more efficient. Together, the SAVES initiative and the CAR-STOP project are revolutionizing the future of automated transportation.
Robert W. Heath, Jr.
Prof. Heath, an expert in millimeter wave communications, holds the Cullen Trust for Higher Education Professorship in Engineering #6 at UT Austin. He received a BS and MS in Electrical Engineering from the University of Virginia in Charlottesville in 1996 and 1997 respectively, and received a PhD in Electrical Engineering from Stanford University in 2002. During that time he served as Senior Consultant at Iospan Wireless, where he helped design and implement the physical and link layers of the first commercial MIMO-OFDM communication system.
In 2002, he joined the Department of Electrical and Computer Engineering at UT Austin, where he is a member of the Wireless Networking and Communications Group, the Data-Supported Transportation and Operations Planning committee, and the founding director of the SAVES research initiative. He is also President and CEO of MIMO Wireless and the Chief Innovation Officer at Kuma Signals.
Prof. Heath’s research interests include wireless communications, signal processing, limited feedback techniques, multihop networking, multiuser and multicell MIMO, interference alignment, adaptive video transmission, manifold signal processing, and millimeter wave communication techniques. He is co-author of two books: Millimeter Wave Wireless Communications and Digital Wireless Communication: Physical Layer Exploration Lab Using the NI USRP.
He has served as Editor, Associate Editor, and Guest Editor on several IEEE publications, and helped chair and lead many international engineering conferences. He has received numerous best-paper awards, and was a 2003 Frontiers in Education New Faculty Fellow. He is also a licensed amateur radio operator, a registered professional engineer in Texas, and an IEEE Fellow.
Prof. Joydeep Ghosh is the Schlumberger Centennial Chair Professor of Electrical and Computer Engineering at UT Austin. He also holds appointments in the Departments of Biomedical Engineering, Computer Science, and the Information, Risk and Operations Management Center in the McCombs School of Business. He received a Bachelors of Technology and a PhD from the University of Southern California in 1983 and 1988 respectively.
He joined the UT Austin faculty in 1988, where he founded and directed the Intelligent Data Exploration and Analysis Lab, and was voted Best Professor in the Software Engineering Executive Education Program. He is now a member of the Wireless Networking and Communications Group and the UT SAVES research initiative, as well as an IEEE Fellow.
Dr. Ghosh’s research interests lie in data and web mining, predictive modeling and analytics, machine learning approaches such as adaptive multi-learner systems, and applications of these research areas to complex real-world problems. He has published over 400 refereed papers and 50 book chapters, and co-edited over 20 books. He has received 16 best-paper awards over the years; served as plenary, keynote speaker, and conference chair at several major conferences; and lectured widely on intelligent analysis of large-scale data. He has served as co-founder, consultant, and advisor to successful startups, including Accordion Health, Stadia Marketing, Neonyoyo, and Knowledge Discovery One, as well as to several large corporations.
