About
Cosmology from weak signals in the microwave sky.
I work on the faint signals hidden in CMB polarization maps, building analysis methods that help turn precision sky measurements into tests of fundamental physics.
I am a postdoctoral fellow at the University of California, San Diego, working on precision cosmology with the Cosmic Microwave Background. My research develops statistical and computational methods for extracting weak polarization signals from survey data, with emphasis on gravitational lensing, B-mode polarization, delensing, and cosmic birefringence.
A central aim of my work is to connect theoretical signatures of fundamental physics with the practical realities of modern CMB observations: foregrounds, instrumental systematics, map-level simulations, likelihood construction, and cross-survey consistency. I contribute to analyses and forecasts for experiments including POLARBEAR, Simons Array, Simons Observatory, LiteBIRD, and CMB-S4.

Constraints on Cosmic Strings from the Curl-Mode CMB Lensing Power Spectrum measured by ACT DR6
A network of cosmic strings is one of the few well-motivated cosmological sources of vector and tensor metric perturbations on the largest observable scales. Such perturbations imprint a characteristic curl component in the deflection angle of cosmic microwave background (CMB) photons that, unlike the scalar lensing potential, vanishes for adiabatic density fluctuations at linear order.
