This is the web page of Priya Natarajan, Professor in the Departments of Astronomy and Physics at Yale University. I am the Director of Graduate Studies for the Department of Astronomy at Yale, a position that I also held during the academic year 2007-2008. I am a theoretical astrophysicist interested in cosmology, gravitational lensing and black hole physics. I was on leave from Yale for the academic year 2008-09 and was the Emeline Bigelow Conland Fellow and Bunting Fellow at the Radcliffe Institute for Advanced Study at Harvard. I have been awarded a Guggenheim fellowship which I will be taking up during the academic year 2010-2011. I was a Whitney Humanities fellow at Yale (2006 - 2007), and a resident faculty fellow of Saybrook College. I am an Associate of the Dark Cosmology Centre, Niels Bohr Institute, at the University of Copenhagen, Denmark.

I have undergraduate degrees in Physics and Mathematics from M.I.T. I am also interested in the history and philosophy of science as well as technology and public policy. I was enrolled in the MIT Program in Science, Technology & Society and the MIT Program in Technology and Public Policy from 1991 to 1993. I did my graduate work in theoretical astrophysics at the Institute of Astronomy, University of Cambridge in England, where I was a member of Trinity College and elected to a Title A Research Fellowship that I held from 1997 to 2003. Prior to coming to Yale, I was a visiting postdoctoral fellow for a few months at the Canadian Institute for Theoretical Astrophysics in Toronto, Canada.
