Research Description

Dr. Lietz works on computational modeling of low temperature plasmas for a wide variety of applications, including medicine (wound healing, cancer treatment), chemical processing (carbon capture and utilization, nitrogen fixation), and the production of computer chips. Computational modeling can be used to explain the underlying physics and chemistry behind behaviors observed in plasma sources, and informs the design and optimization of these plasma sources for each application.
