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 nucleosynthesis, radiative and convective energy transport and equilibrium, construction of stellar models for pre-main sequence and main sequence stars.
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.
We provide interactive demonstrations, lectures, question and answer panels, and star gazing events free of charge to any group in Oklahoma. See this website for more information.
