Dr. Rohatgi received the B.S. (E.E.) degree from Indian Institute of Technology in 1971, the M.S. (Materials Engineering) from Virginia Polytechnic Institute and State University in 1973, and the Ph.D. in Metallurgy and Materials Science from Lehigh University in 1977.

He joined the Westinghouse Research and Development Center in Pittsburgh, Pennsylvania in 1977 and became a Westinghouse Fellow while working on the science and technology of photovoltaic and microelectronic devices.

Dr. Rohatgi joined the ECE faculty at Georgia Tech in 1985 and started a program on photovoltaics, which has become one of the best in the country. He has become an internationally recognized leader in photovoltaics. He is the founding director of the first university-based DOE Center of Excellence in Photovoltaic Research and Education. He is the author of more than 300 publications and holds 10 U.S. patents. Dr. Rohatgi has received numerous awards and distinctions from professional societies and Georgia Tech. He is the founder and CTO for Suniva.
