Tristan Tayag has been a member of the faculty of the Department of Engineering at Texas Christian University since August 1997. He received his B.S.E.E. and M.S.E. degrees from the Johns Hopkins University in 1986 and 1987, respectively. Tristan spent a year and a half as an associate engineer at the Applied Physics Laboratory before earning the Ph.D. degree in Electrical Engineering at the University of Virginia in 1991. From 1991 to 1997, Tristan worked at the Army Research Laboratory where he served as team leader of the Integrated Optics Team.
