Research Background & Future Projects

During my PhD at Auburn University, I worked on Applying Nonextensive Statistics to plasma physics which involves testing with simulation and applying to low temperature plasma data. My research aimed to better formulate the theory of how nonextensive statistics can resolve issues such as long-range collisions and correlations from many body collisions in kinetic theory of plasmas. Using Smilei to simulate plasma conditions similar to low temperature plasmas (also known as nonthermal plasmas because there is a temperature difference between the electrons and ions), I tested the hypothesis that this nonequilibrium condition causes the energy distributions of the particles to follow the form presented in Tsallis' Nonextensive Statistics. While there exist a couple dozen papers on using nonextensive statistics to measure or predict plasma properties, there is not a well formulated fundamental theory describing how and why it works. This research contributed to understanding processes that use low temperature plasma devices for many applications such as biomedical and agricultural application of APPJs, materials and etching, dusty plasma, ionosphere and solar-terrestrial weather, and more.

I worked on PIC simulation of Highly Magnetized Low Temperature (HMLT) plasmas during my postdoctoral research at Auburn using Smilei and continue to work on Plasma Simulations using a variety of open source codes.I am now developing the Appalachian Plasma Learning Device, a small plasma experiment for teaching purposes at Tri-County Technical Community College in Murphy, NC, where I will serve as head of physics. This device will help students understand fundamental plasma physics concepts through hands-on experimentation.
