I'm a theoretical astrophysicist lucky enough to get to work on big questions like "how did we go from the Big Bang to the Universe we see today." I love the collaborative aspects of science, and the chance to work in groups with different students and postdocs and colleagues with a broad spectrum of backgrounds and different perspectives.

My primary research interests are: Galaxy formation and evolution. Star formation and originsof stars and planets. Inter-stellar, circum-galactic, and inter-galactic medium physics. Cosmic rays. Nature of dark matter, astrophysical dark matter constraints and tests. Origins, growth, and evolution of super-massive black holes, AGN and quasars. Astrophysical turbulence and space plasma physics. Large-scale structure and cosmology. Planetesimal formation and astrophysical dust and particle dynamics. Numerical methods for astrophysics and space plasmas. "Feedback" processes on astrophysical scales.
