I am an assistant professor at OU Department of Physics and Astronomy. I enjoy observing the Universe from quiet places on top of 7-14 thousand feet high mountains in Arizona, Chile, Hawaii, and Texas. I received a PhD in Astronomy from UT Austin with a university-wide outstanding dissertation award. I worked as a Columbus Fellow at the Ohio State University and Spitzer Fellow at the Harvard-Smithsonian Center for Astrophysics. In 2011, I was awarded the Paul Hertelendy prize for my work on short period binary white dwarf stars. I am a member of the LSST Science Collaboration (Stars, Milky Way, and Local Volume) and the eLISA Ultra-Compact Binaries Working Group. I thank the NSF and NASA for supporting my research.
Teaching: AST 5473 - Stellar Interiors - Fall 2014
Evolution and energy balance of stars including gravitational attraction, nucleosynthesis, radiative and convective energy transport and equilibrium, construction of stellar models for pre-main sequence and main sequence stars, and the theory of giants and white dwarfs.
Public Star Party
Every Wednesday night while the university is in session, we are hosting a Free Public Star Party at OU's campus telescope. Here is the information on the Star Party.
