affiliations:

assistant professor, department of physics, columbia university
associate research scientist, flatiron institute center for computational astrophysics (part of the simons foundation)

research interests:

My research is in physical cosmology. I analyze cosmological data to search for evidence of new physics and to understand processes involved in structure formation. Much of my work focuses on the cosmic microwave background radiation. I am a member of the Atacama Cosmology Telescope, Simons Observatory, and CMB-S4 collaborations.
