Research

I am interested in theoretical and observational cosmology, primarily as relates to how we can learn about cosmology and fundamental physics through observations of the Cosmic Microwave Background (CMB) and Large Scale Structure.

Currently I am mostly working on the CMB side, with data from Planck and the latest ground-based data from ACT, and I am a member of the Simons Observatory Collaboration. I have also done some work on studying systematics for space-based weak-lensing surveys.
