Brenton Knuffman is a Visiting Researcher in the Alternative Computing Group and a co-founder of zeroK Nanotech Corporation. He received a B.S. in Physics from Loyola University Chicago and a Ph.D. in Applied Physics from the University of Michigan, where his dissertation focused on studies of cold Rydberg atoms and ultracold plasmas. He then worked as a CNST/UMD Postdoctoral Researcher in the Electron Physics Group developing a new type of ion microscope that uses photo-ionized, laser-cooled atoms as its source. He is currently working with Jabez McClelland under a cooperative research and development agreement (CRADA) constructing a prototype of a low-temperature ion source, which utilizes the extremely cold temperatures attainable with laser cooling to produce a highly collimated, bright ion beam.
