I am a postdoctoral fellow in the Particle Physics and Cosmology group of Professor Dominik Schwarz at Universität Bielefeld in Germany. I received my Ph.D from the Department of Physics, University of Florida in August 2007. My thesis advisor was Professor Pierre Sikivie. My research interests include dark matter caustics, dark matter detection, the effects of dark matter annihilation on stars, reionization, and the Hydrogen 21cm line.
