Neelima Sehgal is an Associate Professor in Physics and Astronomy at Stony Brook University. She is on sabbatical at the Center for Computational Astrophysics from Fall 2018 to Fall 2019. Her research interests are understanding the fundamental physics properties of our Universe, especially its origin and particle constituents. Her primary tool to answer these questions is studying the Cosmic Microwave Background (CMB), which is the oldest light in the Universe. The CMB contains the imprint of neutrino properties, dark matter, dark energy, and the history of the infant Universe. She theoretically develops ways to disentangle these signals encoded in the CMB, and applies these techniques in analysis of new CMB data. More recently, she has been focusing her efforts on designing new CMB instrumentation that could answer a broad range of scientific questions. She is also interested in developing new particle detectors, using quantum information devices. She received her B.S. in Physics and Mathematics from Yale University and her PhD in Physics and Astronomy from Rutgers University. She was a postdoctoral fellow at Stanford and Princeton Universities before joining the faculty at Stony Brook in 2012.
