Welcome to my web page! I am an assocciate professor at the Physics and Astronomy departments of the University of Arizona. I am also a member of the Theoretical Astrophysics Program. My research focuses on the physics of neutron stars and black holes, the properties of magnetohydrodynamic turbulence in accretion flows, the testing of the theory of general relativity in the strong-field regime, and the physics responsible for the accelerating universe. I routinely solve problems that involve hydrodynamics and photon transport in extreme physical conditions, using both analytical and numerical tools. |
I collaborate closely with the graduate and undergraduate students in my research group. In the summer of 2003, we purchased a 32-proc Beowulf cluster, which we use extensively in our research. Our theoretical studies are also closely related to observations made with X-ray telescopes, such as the Rossi X-ray Timing Explorer, Chandra X-ray Observatory, and XMM-Newton. I regularly teach undergraduate and graduate classes in the Physics and Astronomy departments. I recently taught a class on Numerical Methods in Physics, on Theoretical Mechanics I and II , on Theoretical Astrophysics, and on General Relativity. |
