Mark A. Neifeld received the B.S.E.E. degree from the Georgia Institute of Technology in 1985 and the M.S. and Ph.D. degrees in Electrical Engineering from the California Institute of Technology in 1987 and 1991 respectively. During the 1985-86 academic year he was also a member of the technical staff in the TRW systems engineering and analysis laboratory in Redondo Beach, California. Following completion of his dissertation at Caltech, he accepted a one year post doctoral position at the NASA Jet Propulsion Laboratories in Pasadena, California where he studied the application of parallel image processing techniques to problems in target recognition and in August 1991 he joined the faculty of the Department of Electrical and Computer Engineering at the University of Arizona. Professor Neifeld is also a member of the faculty of the Optical Sciences Center at the University of Arizona and has co-authored more than 50 conference and journal papers in the areas of optical storage, parallel coding and signal processing, optoelectronic device simulation and CAD, computer generated holography, character recognition, neural networks, and optical processing systems and his thesis work focused on the use of parallel access optical memories for image pattern recognition. He presently directs the Optical Computing and Processing Laboratory within the ECE Department at the University of Arizona and serves as a Topical Editor for Applied Optics.
