The main question driving my work is: What is dark matter?
As a theoretical dark matter (astro)physicist, my methods for answering this question involve making predictions for experiments and observations for particular models of dark matter and galaxy evolution physics. I like to use both analytic and computational methods (often involving the supercomputers at the Ohio Supercomputer Center) to make my predictions. Because of my eagerness (impatience?) to test my predictions, my research operation has an increasing observational footprint. Members of my research group are active in both theory and observations, and at the interfaces of dark-matter physics, galaxy evolution, and cosmic-ray astrophysics.
