I am an Assistant Professor of Physics and Astronomy at the University of Alabama in Huntsville (UAH).
My research concentrates on all aspects of galaxy clusters (the largest collapsed structures in the universe), from the outskirts where they are continuing to form from the cosmic web, to gas sloshing produced by galaxy cluster mergers, to studying AGN feedback in cluster cores, focusing on their X-ray emission.
