Vicky Kalogera, Ph.D.

Vicky Kalogera is a leading astrophysicist recognized for her pioneering work on compact objects — black holes, neutron stars, and white dwarfs — and for her leadership in gravitational-wave astrophysics. She earned her B.S. in Physics from the University of Thessaloniki, Greece, and her Ph.D. in Astronomy from the University of Illinois at Urbana-Champaign, followed by a postdoctoral fellowship at the Harvard-Smithsonian Center for Astrophysics.

Kalogera is the Daniel I. Linzer Distinguished University Professor in the Department of Physics and Astronomy at Northwestern University. She co-founded and directs the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA), fostering collaborations across astrophysics, data science, and computation. Her recent leadership includes chairing Northwestern’s Data Science/AI Steering Committee and directing the NSF-Simons AI Institute for the Sky (SkAI), which develops advanced AI tools for astronomy.

Kalogera’s research bridges stellar evolution, gravitational-wave sources, and data-driven astrophysics, integrating machine learning and high-performance computing. She is a key member of the LIGO Scientific Collaboration, contributing to the first direct detection of gravitational waves in 2015. That first detection opened a new window onto the universe uniquely revealing powerful mergers of black holes. Later detections enabled coupled gravitational-wave and electromagnetic-wave, multi-messenger, observations revealing the sites of gold and other heavy metals production. She is at the forefront of this emergent field of gravitational-wave astronomy and uses data analysis and astrophysical modeling to understand the universe’s population of black holes and neutron stars. Over the past decade she has co-led innovative research employing advanced data-science and artificial intelligence methods in computational astrophysics challenges.

A 2004 Cottrell Scholar, Kalogera has received numerous honors recognizing her scientific achievements, notably the Hans A. Bethe Prize (APS, 2016), Dannie Heineman Prize for Astrophysics (AIP & AAS, 2018), Guggenheim Fellowship (2021), and several collaborative honors including the Special Breakthrough Prize in Fundamental Physics (2016) and the Bruno Rossi Prize (2017). She is an elected member of the National Academy of Sciences (2018) and the American Academy of Arts and Sciences (2021), and a Fellow of the APS, AAAS, and AAS.
