Kyle Kremer is an assistant professor in the Department of Astronomy & Astrophysics at the University of California, San Diego.

His research group at UCSD builds connections between the fields of stellar dynamics and compact object astrophysics. Areas of expertise include N-body simulations of dense stellar clusters, detection of compact object binaries via gravitational waves (LIGO & LISA), and high-energy transient phenomena such as tidal disruption events and fast radio bursts. He is also broadly interested in binary star evolution, hydrodynamics of stellar mergers, millisecond pulsars, intermediate-mass black holes, X-ray binaries, and observational searches for black hole binaries. 

Kremer grew up in Ohio and attended Northwestern University for his undergraduate studies, where he double-majored in physics and music performance. After completing his undergraduate degree, he spent three years pursuing a career as an orchestral musician, earning a Master of Music degree at the Colburn School in Los Angeles in 2015, before returning to Northwestern to complete his PhD in astronomy in 2019 under the advisement of Fred Rasio. Following his PhD, he moved back to Southern California as an NSF Postdoctoral Fellow and later as a NASA Einstein Fellow at Caltech and Carnegie Observatories. He joined the UCSD faculty in Fall 2024.
