Arun Majumdar, named Director of the Environmental EnergyTechnologies Division at Lawrence Berkeley National Laboratory in October, 2007, is also the Almy & Agnes Maynard Chair Professor in Mechanical Engineering at the University of California, Berkeley. Professor Majumdar's research interests are in the broad area of energy conversion, and heat and mass transport in nanostructures. Of particular interest are heat-electricity conversion in solid-state thermoelectric engines and refrigerators, as well as electrochemical transport in nanofluidic devices.

Arun Majumdar is a member of the Nanotechnology Technical Advisory Group to the President's Council of Advisors on Science and Technology (PCAST). He is a recipient of the Institute Silver Medal (IIT-B) (1985), NSF Young Investigator Award (1992-97), ASME Melville Medal (1992), Gustus Larson Memorial Award of the ASME (2001), Distinguished Alumni Award from IIT-B (2002), and the ASME Heat Transfer Memorial Award (2006). He is a fellow of ASME and AAAS, and is a member of the US National Academy of Engineering.

Professor Majumdar received a B.Tech in Mechanical Engineering from the Indian Institute of Technology, Bombay (IIT-B) in 1985, and a PhD in Mechanical Engineering from Berkeley in 1989. He has been on the faculty at UC Berkeley since 1997, after serving on the faculties of Arizona State University (1989-92) and University of California, Santa Barbara (1992-96).
