❝
I am an Assistant Professor in the Departments of Astronomy and Physics at the University of Arizona, and one of the 5 core faculty of the Theoretical Astrophysics Program at Arizona. I carry out research at the interface of gravitational physics and astrophysics. The goal of my work is to understand strong field gravitation and to solve long-standing astrophysical puzzles. Much of my work aims at modeling gravitational wave sources and multimessenger sources, especially those currently observed by both the LIGO/Virgo instruments, and a number of missions observing across the electromagnetic spectrum.Show Less
