Dr. Jessing joined the faculty in 2013. He is currently investigating the unique electrical and optical properties of porous silicon, with an eye to the development of several high impact technologies in the fields of sensors, computing, and instrumentation. Jessing has considerable experience in research and manufacturing environments, including the development, fabrication, and characterization of novel electronic & optical materials/devices, microelectromechanical systems (MEMS) and integrated microelectromechanical systems (IMEMS), novel methods of characterization and design of microsensors, application of thin film processing techniques to the development of bio-MEMS and bio-electronic components, characterization and modeling of process dependent radiation effects in CMOS, and process/device modeling. Prior to joining the faculty at Fort Lewis College, Jessing was the vice president of research and co-owner of Sitanium, a company involved in the development and technology transfer of novel microfabricated medical devices, an assistant professor at Boise State University, and a technical staff member at Sandia National Laboratories in Albuquerque. He is a member of the Institute for Electrical and Electronics Engineers and the Phi Kappa Phi Honor Society.
