Research Interests

I am interested in anything astronomy. My research in the past has been in the area of particle transport in plasma related to solar flares, and X-ray data analysis for a special class of neutrons stars called magnetars. I am currently foraging into the field of radio astronomy with a student here at GVSU. For details please click on the research statement below.
