Brief writeup on area of specialization/awards/achievements:
 

I have done most of my research work in the field of Phonon Conductivity of Solids as a research scholar and post doctoral fellow. After joining as a permanent faculty member in 1982 I changed my research area to the theoretical study of photonic devices like solar cells and photo detectors. Presently I am working in the field of quantum well infrared photo detectors and photo refracting materials. In teaching I am interested in Electronic Devices, Circuits and Communication (both analog and digital). Semiconductor physics, Microprocessor, Microcontrollers and Microcomputers.

I have been serving as a guest faculty in the department of Computer Science B.H.U. since 1990. I also served as the Head of Department of Computer Science from May 2005 to August 2006.
