I was born in Hue and grew up in Da Nang, Viet Nam, and Tahlequah, OK. I received the B.S. degrees in electrical engineering and mathematics from MIT (1983), the M.S. and Ph.D. degrees from Caltech (1991) and Rice University (1996), respectively, all in electrical engineering.
From 1983 to 1985, I was an EMC engineer with Xerox Corporation in El Segundo, CA where I performed electromagnetic compatibility (EMC) design and testing of printer and copier products. I was an RF/microwave engineer with the Hughes Aircraft Company in 1985, working on the vehicular JTIDS radio program, and then with the Jet Propulsion Laboratory from 1985 to 1991 in Pasadena, CA. There I worked on the receiver and exciter subsystems of the Deep Space Networks of NASA. This included developing low noise, high frequency stability S- and X-band test signal generators for the Radio Science experiments during the Neptune encounter of the Voyager II spacecraft. From 1991 to 1996, I was an electronics engineer/program manager with the Space Vehicle Directorate at the USAF Phillips Laboratory in Albuquerque, NM.
Since 1996, I have been an assistant professor in the Department of Computer and Electronics Engineering at University of Nebraska-Lincoln. My current research interests are in RF and optical communications, application of spread spectrum to wireless and fiber optic communications, signal processing and transform techniques.
