Personal Information

I am a graduate student in the Florida State Physics department, and will graduate in May 2013. I got my undergraduate degree from UMASS, Amherst in Astrophysics, with minors in Physics, Math, and Music in 2006. I recieved a Masters degree in Astronomy and Astrophysics from Penn State, 2008. My primary research interests are mathematical physics, classical and quantum gravity, noncommutative geometry and high energy physics. My current work involves studying the geometry and topology of models for the gravitational field. Specifically, I am looking at the effects of exotic smooth structures on some basic results from quantum gravity, and I am also working on the topspin formulation of Loop Quantum Gravity. On this page you will find links to my research projects, some teaching resources, and other interesting links related to physics, astronomy, and non-science related topics. Also, here is my Curriculum Vitae.
