I am currently an associate professor in the Department of Physics and Astronomy at George Mason University . From 1999 through 2003, I was a postdoc at the Canadian Institute for Theoretical Astrophysics ( CITA ), at the University of Toronto . I received my Ph.D. in physics in 1999 from Princeton University , under the supervision of Bruce T. Draine . My research focuses on physical processes associated with cosmic dust.
