- Dr. Lakdawala received his BE degree from Bangalore University, India, in 1972, the ME degree from the Indian Institute of
Science, India, in 1974, and the Ph.D. from the University of Liverpool, United Kingdom, in 1980, all in electrical engineering.
He has worked as an Assistant Development Engineer with M/s Jyoti Limited in their R & D Center in instrument transformers
division. He joined the Department of Electrical Engineering at the University of Liverpool as a Senior Research Associate
in 1980. In 1982 he joined the Atomic Molecular and High Voltage Physics group at the Oak Ridge National Laboratory as a Post-Doctoral
Research Associate. His publications include articles on electron attachment in fluorine compounds, breakdown studies in compressed
gases and vacuum, material characterization and simulation studies in compound semiconductors, and high power semiconductor
switches. Dr. Lakdawala joined Old Dominion University in the Fall of 1983. He served as the Graduate Program Director from
1988 -98. He is presently the Chief Departmental Advisor and an Associate Professor of Electrical and Computer Engineering.
