This page is somewhat boring. I like to think that I am not. In the past, I have made festive and exciting webpages but those days may be behind me. Or maybe not. Quick Bio: I joined the Astrophysics Group in the Physics department at Drexel in the fall of 2001. I was extremely involved in the construction of the new Joseph R. Lynch Observatory. I am also very involved in teaching and curricular issues. I have served in the past on the College of Arts & Sciences undergraduate curriculum committee, and the Physics department curriculum committee, which I now chair. In Fall, 2002, we instituted major changes in the curriculum, including the introduction of the Contemporary Physics sequence. I am also director of undergraduate studies, so if you have any questions about your degree, please be sure to ask. Finaly, I am a member of the faculty senate, so if you're a faculty member with a concern, let's see what we can do. I am also very involved in research. Most of my work centers around cosmology in some way or another. I am interested in gravitational lensing, and, in particular, in extracting additional information out of weak lensing signals, and have started looking at the question of combining weak and strong fields. In 2001, Michael Vogeley and I (ably assisted by undergrads Greg McIvor, Greg Byrne, and Ernie Mamikonyan) put together the "Frinkiac" a 48 node, 96 processor (1.4 GHz/chip) Beowulf cluster. It has been used for N-body simulations as well as MHD calculations of the coronal mass ejections, and is the centerpiece for BASIN (Beowulf Analysis Symbolic INterface), a computational projected funded by the NSF for 5 years of development. Check here for progress, downloads, and documentation. Previously, I worked as a "Gibbs Lecturer" (my fancy postdoc title) at Yale University with Priya Natarajan, and in the process, developing a cool little java program, the Yale Observatory iMAge Manipulation Application (YOMAMA) . Prior to that, I did my graduate work at Princeton University under David Spergel. I did my thesis on "Running the Universe Backwards in Time," in which I developed a Least Action method for running large N-body simulations self-consistently in reverse. I also came dangerously close to winning the departmental Table Tennis Tournament twice. Completing our trip back in time, I did my undergraduate work at Boston University, majoring in Astronomy and Physics, with minors in Math and Religion. My senior thesis work was with Tereasa Brainerd, running numerical simulations of clusters.
