- Received his BS degree from the University of Miami, Florida, in December 1979, his MS and Ph.D. degrees from the University
of Illinois, Urbana, Illinois in January 1982 and January 1985, respectively, all in electrical engineering. Upon graduation,
he worked as a visiting assistant professor at the University of Illinois conducting research in the areas of gas discharges
and thin film deposition. In December 1985, he joined the Laboratory for Laser Energetics at the University of Rochester as
a scientist. At Rochester he worked on femtosecond and picosecond laser probing of electronic and structural properties of
material surfaces and thin films. He joined Old Dominion University in December 1992 and he is currently a professor. His
current research interests are mainly in ultrafast laser probing of surface and thin film reactions. He authored and co-authored
over 70 refereed journal articles and holds 2 patents. In 2000, he was the recipient of the 16th Annual Faculty Research
Award at Old Dominion University.
