To date, most of my research has focused on the secondary anisotropies of the cosmic microwave background, specifically the Sunyaev-Zel'dovich (SZ) effects. This work has been done as part of the analysis team of the Atacama Cosmology Telescope (ACT).

Recently, my work with the ACT team, in collaboration with the BOSS survey, has led to the first ever observation of the kinematic Sunyaev-Zel'dovich effect. A nice summary of this research is available on Astrobites.

I'm currently working with Uros Seljak on extending my previous analysis of the kinematic SZ effect. I began my work in this area as part of my senior thesis at Princeton, where I worked with David Spergel on detecting the thermal and kinematic SZ effects from luminous red galaxies in the ACT data.
