Until late 2006, when I left academia to pursue work in biotechnology, I worked as an educator and researcher in astrophysics. My research involved studies of clusters of galaxies at X-ray and radio wavelengths. Most of my work focused on cluster mergers, but I also studied cooling flow clusters. Most recently, I studied the effects of heating from AGN, mergers, and other sources on the evolution of poor clusters.
The Bowdoin College web site published an article about my work in the spring of '06.
As part of my research, I created a number of useful software tools. In the spirit of keeping the scientific process open, I licensed some of the most useful ones under the GPL.
