Professor Kara is an observational astrophysicist, working to understand the physics behind how black holes grow and affect their environments. She has advanced a new technique called X-ray reverberation mapping, which allows astronomers to map the gas falling on to black holes and measure the effects of strongly curved spacetime close to the event horizon. She also works on variety of transient phenomena, such as tidal disruption events and Galactic black hole outbursts. She is a NASA Participating Scientist for XRISM Observatory, a joint JAXA / NASA X-ray spectroscopy mission, and co-chairs the supermassive black hole working group.
Erin Kara is originally from Bethlehem, Pennsylvania, and attended Barnard College, where she obtained a B.A. in physics with a minor in art history. After graduating in 2011, she moved to the United Kingdom on a Gates Cambridge Scholarship to study for a Masters and a PhD from the Institute of Astronomy at the University of Cambridge. In 2015, she was awarded a NASA Hubble Postdoctoral Fellow, which she took to the University of Maryland and NASA’s Goddard Space Flight Center. In 2018, she became the Neil Gehrels Prize Postdoctoral Fellow at the University of Maryland, and joined the faculty of MIT as an Assistant Professor of Physics in July 2019.
