She is a theoretical astrophysicist interested in cosmology, gravitational lensing and black hole physics. In addition to her academic position at Yale, she also currently holds the Sophie and Tycho Brahe Professorship of the Dark Cosmology Center, Niels Bohr Institute, at the University of Copenhagen, Denmark.

She was on leave from Yale to take up her Guggenheim Fellowship during the academic year (2010 - 2011). She was a JILA Fellow at the University of Colorado at Boulder in September and October, 2010. From November, 2010 onwards she was a visiting professor at the Institute for Theory and Computation at the Harvard Smithsonian Center for Astrophysics in Cambridge. She was also enrolled as a graduate student in the Spring (2011) at the Program in Science, Technology and Society at MIT. She was a fellow at the Rockefeller Bellagio Center in Italy during May-June 2011.

Priyamvada was the Director of Graduate Studies for the Department of Astronomy at Yale during the academic years 2009-2010 and 2007-2008 and is the Director for Graduate Studies for Admissions in 2011-2012. In 2008-2009, she was the Emeline Bigelow Conland Fellow at the Radcliffe Institute for Advanced Study at Harvard. She was a Whitney Humanities fellow at Yale (2006 - 2007), and a resident faculty fellow of Saybrook College. Priya is a member of the Publications Committee of the Yale Press, a member of the Terry Lectureship Committee and she also serves on the Yale College Science Council as well as on the Executive Committee of the South Asian Studies Council and India Initiative at Yale.

Priya is the current chair of the Womens Faculty Forum (WFF) at Yale. She was on the Steering Committee of the Womens Faculty Forum from 2003-2010. She is deeply interested in Gender Parity issues in the Academy. Along with Judith Resnik and Reva Siegel at the Yale Law School, she is co-organizing the first Gruber conference titled "Parity as Practice: The Politics of Equality" from 30 March - 1 April, 2012.

She is invested in the public dissemination of science and is on the Advisory Board of NOVA ScienceNow. Priya is actively engaged in developing strategies to enhance numerical and scientific literacy for the public at large.

Priya has undergraduate degrees in Physics and Mathematics from M.I.T. While at M.I.T she was awarded the Peter J. Eloranta Award for excellence in undergraduate research, the Carroll Wilson Award, a Burchard fellowship and the Ida Green Fellowship. She is also interested in the history and philosophy of science as well as technology and public policy and was enrolled in the MIT Program in Science, Technology & Society and the MIT Program in Technology and Public Policy from 1991 to 1993. She was recently awarded a Master's Degree (S.M.) from MIT's Program in Science, Technology and Society in September 2011. She did her graduate work in theoretical astrophysics at the Institute of Astronomy, University of Cambridge in England, where she was a member of Trinity College and was elected to a Title A Research Fellowship that she held from 1997 to 2003. She was the first woman in Astrophysics to be elected a fellow of Trinity College, Cambridge. Prior to coming to Yale, she was a visiting postdoctoral fellow for a few months at the Canadian Institute for Theoretical Astrophysics in Toronto, Canada.

Priya was the 2009 recipient of the India Abroad Foundation's "Face of the Future " Award. She was also the 2009 recipient of the award for academic achievement from the Global Organization for the People of Indian Origin (GOPIO). Priya was elected a fellow of the American Physical Society in 2010. She was also elected a fellow of the Explorers Club in 2010. In January 2011 she was awarded an India Empire NRI award for Achievement in the Sciences in New Delhi, India. She is the Caroline Herschel Distinguished Visitor at the Space Telescope Science Institute in Baltimore for 2011-2012. Along with Denys Turner and Michael della Rocca, Priya organized an inter-disciplinary conference at Yale titled Why is there anything in the Universe? that was held at the Greenberg Center from October 6 - 9, 2011.
