Welcome to my website. I am currently a second-year PhD candidate in Astrophysics at Harvard. I am interested in a wide range of topics in physical and observational cosmology. I am currently working with Prof. Daniel Eisenstein on the methodology and applications of the galaxy three-point correlation function (3PCF) in the squeeze limit, specifically in the context of constraining the galaxy-halo connection. We are also broadly interested in methodologies that improve clustering measurements and their interpretations.

I am currently an observer/telescope operator at Harvard Observing Project (HOP), where we host open observing nights to look at fun yet scientifically interesting targets. I am also a founding member of Open Labs At Harvard, with the goal of promoting science and research education among underpriviledged K-12 students in the Greater Boston area.

Before Harvard, I got my Bachelors degree in Astrophysics at Princeton, where I worked on various exciting projects such as identifying obscured quasars in SDSS, looking for ultra diffuse galaxies in HSC, and simulating progenitor gas clouds in the early Universe. 

Aside from work, I enjoy tennis, DJing, and good sushi.
