Professor John Williams' research interests include modeling of erosion phenomena on ion thruster components such as ion extraction grids and hollow cathodes and experimental evaluation of plasma and ion beam interactions with materials for both aerospace and terrestrial applications. Professor Williams, a graduate of Colorado State University, worked at the Hughes Research Laboratory and the Electric Propulsion Laboratory before joining the mechanical engineering department in 2002.
Research Scientist II
For his doctoral research, Dr. Farnell studied the measurement and formation of high energy ions formed near a hollow cathode. He is presently working to expand the depth of CSU's probe diagnostic abilities and knowledge.
Research Scientist II
Dr. Farnell's doctoral research dealt with the simulation of ion thruster optics. Currently, he is applying simulation techniques to additional areas of research interest.
Kirk J. Boehm
At the beginning of 2015 Kirk received his Dipl.-Ing. in Mechanical Engineering with a major in Aerospace Technologies from the Technical University Dresden. His doctoral research focuses on selective electron beam sintering in combination with hollow cathodes. His research interests include plasma technologies, satellite technologies, and manned space missions to the Jupiter system.

Paul J. Wilbur
Professor Paul J. Wilbur contributed 40 years of service to the Mechanical Engineering department at CSU. Reflecting his lifetime contributions to the electric propulsion community, he was awarded the "Medal of Outstanding Achievement in Electric Propulsion" in 2007. Professor Wilbur's research applied broad beam ion sources to applications such as spacecraft propulsion, surface modification of materials using ion beams, and plasma contacting to control the potentials of spacecraft. His most recent research focused on the development of emissive membranes, a promising new technology in electric propulsion.
