Biographical Information

Ralph Etienne-Cummings received his B. Sc. in physics, 1988, from Lincoln University, Pennsylvania. He completed his M.S.E.E. and Ph.D. in electrical engineering at the University of Pennsylvania in December 1991 and 1994, respectively. Currently, Dr. Etienne-Cummings is a professor of electrical and computer engineering, and computer science at Johns Hopkins University (JHU). He is the former Director of Computer Engineering at JHU and the Institute of Neuromorphic Engineering (currently administered by University of Maryland, College Park). He is also the Associate Director for Education and Outreach of the National Science Foundation (NSF) sponsored Engineering Research Centers on Computer Integrated Surgical Systems and Technology at JHU. He has served as Chairman of the IEEE Circuits and Systems (CAS) Technical Committee on Sensory Systems and on Neural Systems and Application, and was re-elected as a member of CAS Board of Governors in 2006. He was also a member of Imagers, MEMS, Medical and Displays Technical Committee of the ISSCC Conference from 1999 – 2006. He is the recipient of the NSF’s Career and Office of Naval Research Young Investigator Program Awards. In 2006, he was named a Visiting African Fellow and a Fulbright Fellowship Grantee for his sabbatical at University of Cape Town, South Africa. He was invited to be a lecturer at the National Academies of Science Kavli Frontiers Program, held in November 2007. He has also won publication awards, including the 2003 Best Paper Award of the EURASIP Journal of Applied Signal Processing, and has been recognized for his activities in promoting the participation of women and minorities in science, technology, engineering and mathematic. His research interest includes mixed signal VLSI systems, computational sensors, computer vision, neuromorphic engineering, smart structures, mobile robotics, legged locomotion and neuroprosthetic devices. He has published ~160 technical articles, 1 book, 7 book chapters and holds 3 patents on his work in these subjects.
