Pallab Bhattacharya received the B.S. degree in physics in 1968, the B.Tech. and M.Tech degrees in radio physics and electronics in 1970 and 1971, respectively, all from the University of Calcutta, India. He received the M.Eng. and Ph.D. degrees from the University of Sheffield, UK, in 1976 and 1978, respectively. From 1978 to 1983, he was a member of the Electrical Engineering faculty at Oregon State University. Since 1984 he has been with the University of Michigan. He was an Invited Professor at the Ecole Polytechnic Federale de Lausanne, Switzerland, from 1981 to 1982. He is currently the Charles M. Vest Distinguished University Professor of Electrical Engineering and Computer Science and the James R. Mellor Professor of Engineering in the Department of Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor. He was an Editor of the IEEE Transactions on Electron Devices and is Editor-in-Chief of Journal of Physics D. He has edited Properties of Lattice-Matched and Strained InGaAs (UK: INSPEC, 1993) and Properties of III-V Quantum Wells and Superlattices (UK: INSPEC, 1996). He is author of the textbook Semiconductor Optoelectronic Devices (Prentice Hall, 2nd edition).

He is a Fellow of the IEEE, the American Physical Society, the Institute of Physics (UK), and the Optical Society of America. His teaching and research interests are in the areas of compound semiconductors, low-dimensional quantum confined systems, nanophotonics and optoelectronic integrated circuits. He is currently working on high-speed quantum dot lasers, quantum dot infrared photodetectors, photonic crystal quantum dot devices, and spin-based heterostructure devices.

Research Interests: Compound semiconductor materials growth and characterization, optoelectronic devices and device physics
