I am a Berkeley Center for Cosmological Physics (BCCP) Fellow at the Lawrence Berkeley National Lab (LBNL) and the Department of Physics, University of California, Berkeley.

The main theme of my research is the connection between the small scale anisotropies in the Cosmic Microwave Background (CMB) radiation and the large-scale structure in the Universe. I am interested in the nature of the secondary anisotropies in the CMB caused by its interaction with the large-scale structure. Specifically,  my work focuses on the gravitational lensing of the CMB and the Sunyaev-Zeldovich (SZ) effect. I enjoy a mix of theoretical, numerical, data-based and observational projects.

I have been a long term member of the Atacama Cosmology Telescope (ACT) team. The ACT is a 6 m telescope in the Atacama Desert in Chile, making observations of the CMB  with arcminute resolution and at millimeter wavelengths. I am deeply involved in analyzing the power spectrum and the lensing signal in the ACT data. A related interest is the study of SZ clusters detected in the ACT maps.
