Benjamin Klein received his B.S. and M.S. in Electrical Engineering from the University of Wisconsin-Madison in 1994 and 1995, respectively. He received his Ph.D. in Electrical Engineering from the University of Illinois – Urbana-Champaign in 2000. The subject of his doctoral dissertation was the theory and modeling of vertical-cavity surface-emitting lasers (VCSELs), which are a class of semiconductor laser used for telecommunications applications.

From 2000-2003, Klein worked as a postdoctoral researcher at the National Institute of Standards and Technology in Boulder, Colorado, working on the modeling and design of semiconductor quantum-dot based devices, including single photon emitters and single electron transistors. From 2003-2020 he was a faculty member at the Georgia Institute of Technology, first on the Savannah campus, and later in Atlanta. At the time of his departure from Georgia Tech, he was an Associate Professor and the Associate Chair for Graduate Affairs in the School of Electrical and Computer Engineering.
