Computational High-Energy Astrophysics

I am currently an astrophysicist at NASA's Goddard Space Flight Center, working on galaxy cluster merger simulations with Maxim Markevitch. I received my Bachelor of Science degree in physics from the University of Illinois at Urbana-Champaign, and my Master of Science and doctoral degrees in astronomy and astrophysics at the University of Chicago, working with Don Lamb. My first postdoc was at the Harvard-Smithsonian Center for Astrophysics.

My main research interests are merging galaxy clusters and the physics of the intracluster medium (ICM), a hot, magnetized plasma that comprises the bulk of the cluster's baryonic material. The ICM radiates in X-rays, and telescopes such as Chandra and XMM-Newton have revealed a wide array of interesting phenomena. You can find out more about my research at this page.

For this research I have been primarily using the FLASH code, developed primarily at the FLASH Center at the University of Chicago, though a substantial portion of the code modules necessary for simulating galaxy cluster mergers was developed by Paul Ricker. I have recently also been using the Enzo and Athena codes for these simulations as well. I am also a contributor to the yt Project, an analysis and visualization system for astrophysical simulation data (yes, that's a mouthful!). I help maintain yt's FLASH and Athena frontends and develop algorithms for visualization and analysis of particle data, mock X-ray observations, and initial conditions generation.
