Biography

Peter G. LoPresti received the B.S.E. degree in electrical engineering from the University of Delaware, Newark, in 1988, and the Ph.D. degree in electrical engineering from The Pennsylvania State University, University Park, in 1994. He came to TU in the fall of 1994, and is currently a Full Professor of Electrical and Computer Engineering. He currently acts as a consultant on the development of three-dimensional displays and optical sensor systems and is the Director of the Optical Networking Laboratory at TU. He has served as a faculty mentor for the Tulsa Undergraduate Research Challenge program since2000, and the IEEE student branch advisor since 1998. His fields of interest include the engineering of optical communications systems; the design and implementation of mobile free-space optical communication networks for disaster recovery, environmental monitoring, and battlefield communication; and optical sensor development for environmental monitoring. He has also performed research in the area of visual prostheses.
