B.S. Engineering Physics w/ Honors, Stanford University, 2010
M.S. Mechanical Engineering, Stanford University, 2012
Chris grew up in sunny Manhattan Beach, California and enjoys a competitive game of beach volleyball. Outside of the lab, you might catch him improvising music with the SImps, Stanford's best (and only) improv group on campus. He decided Stanford was much too nice to leave, so he signed on to stay another 5 years or so.

Research Activities:
Chris' undergraduate research focused on designing, testing, and simulating the Stanford Diverging Cusped Field (DCF) plasma thruster. His graduate research involves experimentally and computationally studying ion dynamics and the magnetized plasma sheath structure found in the thruster's main channel.

B.S. in Nuclear Engineering, University of Florida, 2014
B.S. in Physics, University of Florida, 2014

Thomas hails originally from the very far reaches of the East Coast in a rural community of Central Florida (2454 miles away from Stanford). While he is not trudging through coursework at Stanford, he enjoys traveling, exercising, and especially watching as many national sporting events as humanly possible.

Research Activities:
Much of the undergraduate research that Thomas focused on was related to atmospheric pressure dielectric-barrier discharges. This led to an intense fascination with plasma physics and a desire for further experimental and numerical research. His current research interests include: pulsed-plasmas, plasma propulsion, Vlasov plasma modeling, magnetohydrodynamics, and the plasma deflagration gun experiment.
