Full name: 
Benjamin D.B. Klein
Job title: 
Adjunct Associate Professor
Technical Interest Groups: Nanotechnology, Optics and Photonics

Benjamin Klein received his B.S.E.E. and M.S.E.E. degrees from the University of Wisconsin, Madison in 1994 and 1995, respectively, and his Ph.D. from the University of Illinois, Urbana-Champaign in 2000. From 2000-2003, Dr. Klein served as a postdoctoral fellow at the National Institute of Standards and Technology in Boulder, Colorado, carrying out theoretical analysis and computer simulations of next-generation semiconductor photonic devices. Dr. Klein first joined Georgia Tech as an ECE faculty member based at the Georgia Tech-Savannah campus in 2003, and in 2012, he transferred to the Georgia Tech campus in Atlanta. Dr. Klein served as the School's associate chair for Graduate Affairs from January 2018-December 2020. In January 2021, he departed from Georgia Tech and became the chair of the Department of Electrical and Computer Engineering at Kennesaw State University.
