Research & Teaching Interests

My main focus here at GVSU is teaching and I enjoy teaching across the broad spectrum of course that we offer here. Because my focus is teaching, the true goal of any research that I do here is to teach our students. I am happy to work with students on any well-thought project. My Ph.D. dissertation work involved magnetohydrodynamic modeling of charged particles in the context of solar physics. Since then I have worked on data analysis of X-rays from magnetars and Bayesian classification in the context of missile defense. Most recently I have begun to dabble in studying the plasma generated in electrical discharges.
