A picture of my face

I am a researcher tackling questions in cosmology and astrophysics. My primary interests are in understanding the initial conditions, evolution and composition of the universe as a whole, including its Dark components and neutrinos. I work very closely with data and have a keen interest in developing principled approaches to statistical analysis of data from cosmic microwave background (CMB) and large-scale structure surveys. These days, together with my collaborators, I spend a good fraction of my time analyzing and extracting science from the Atacama Cosmology Telescope (ACT) using pipelines we're building for the upcoming Simons Observatory.
