Quick Bio: I joined the Astrophysics Group in the Physics department at Drexel in the fall of 2001. I am currently Director of Undergraduate Studies, so if you are a student with a question about a course, a faculty member from another department with a question about our offerings, or a prospective student, I'm a good person to ask. 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 of galaxy clusters. I've also gotten interested in strongly lensed systems as well. See my publication list below for some recent projects. I've also done a lot of popularization. My first book (at least, my first official book for which I wasn't a ghostwriter) came out in March of 2010: "A User's Guide to the Universe." I am currently working on a second, "The Universe in the Rearview Mirror," which will be published by Dutton in 2013, but if you can't wait until then, I write an Ask a Physicist column for io9. Previously, I was a "Gibbs Lecturer" 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 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.
