Benjamin Williams

Benjamin Williams

Professor and Lab Director

Benjamin Williams obtained his B.S. in Physics at Haverford College in 1996, where he performed thesis work on mixing in two-dimensional turbulent fluid flows, for which he received the American Physical Society Apker prize. He then received his M.S. in 1998 and Ph.D. in 2003 from the Massachusetts Institute of Technology in the department of Electrical Engineering and Computer Science. During this time he developed some of the first terahertz quantum cascade lasers. Prior to joining UCLA, Williams was a Postdoctoral Associate in the Research Laboratory of Electronics at MIT. Since 2007, Prof. Williams has been faculty in the Department of Electrical and Computer Engineering at UCLA, and is a Henry Samueli Engineering Fellow. He was awarded a 2008 DARPA Young Faculty Award, the 2012 NSF CAREER award, and the 2013 Presidential Early Career Award for Scientists and Engineers (PECASE).
