Before coming to UMBC in 1999, I was an associate professor at the University of North Dakota and visiting assistant professor at UCLA. After graduate school, I was a post-doc at the Space Telescope Science Institute and worked on the Hubble Space Telescope.
My research field of interest is high energy astrophysics. In particular, I study the formation of large scale structure in the Universe: galaxy clusters, superclusters, and filaments. Structure formation involves energetic collisions of massive objects that produce a ~100 million Kelvin plasma as well as relativistic protons and electrons. These in turn produce a characteristic X-ray signature that I use to study the physics of structure formation.

This X-ray image shows a comet-like blob of gas about five million
light-years long hurtling through a distant galaxy cluster at over 500
miles per second (nearly 1,000 km/s). The comet is confined to the orange
regions in this image. The head is the lower right, with reddish areas.
The tail fans outward because there is less pressure to confine it.
