I'm an Assistant Professor in the Physics and Astronomy Department and Deputy Director of the Galactic Center Group at UCLA. My research interest is in understanding the formation of the nuclei of galaxies, the physics and astrophysics of supermassive black holes, and machine learning applications in astronomy.

My research interest is in understanding the formation of the nuclei of galaxies - I'm currently studying the composition and star formation history of the Milky Way nuclear star cluster and how these stars interact with the supermassive black hole at the Galactic center. I also use the orbits of these stars to test Einstein's General Theory of Relativity around our supermassive black hole. I'm also interested in the dynamics of nearby Milky Way dwarf galaxies and how we can use them to study cosmology. I am primarily an observer, using both space-based telescopes such as the Hubble Space Telescope, and adaptive optics on ground-based telescopes like the Keck Telescopes and Gemini to obtain precise photometry and kinematics. I have also been working on a data simulator and science cases for the Infrared Imaging Spectrograph (IRIS) for the future Thirty Meter Telescope (TMT).

I am currently organzing the UCLA Astronomy Machine Learning Reading Group .
I got my undergraduate degrees in Physics and Astrophysics at UC Berkeley in 2004 and my PhD at UCLA in 2010. I was a TMT postdoctoral fellow at UC Irvine until 2012, when I joined the Dunlap Institute as a Dunlap Fellow until 2014. I returned to UCLA in 2015 as a research scientist and joined the Physics and Astronomy Department faculty in 2020.
