About

Hello! I am a third year Ph.D. candidate in Physics at McWilliams Center for Cosmology, Carnegie Mellon University, where I am advisded by Rachel Mandelbaum studying observational cosmology.Prior to graduate school, I recieved my B.S. in Mathematics and Physics (specialization in Astrophysics) at the Univeristy of California, Irvine.

Research

My primary research area is weak gravitational lensing with a particular interest in utilizing statistical and machine learning methods to perform cosmological analysis on large survey dataset, such as the Vera R. Observatory's Legacy Survey of Space and Time (LSST), the Subaru Telescope's Hyper Suprime-Cam (HSC), and the Roman Space Telescope. My research focuses on 1) turning large dataset into inferences on cosmological models using statistical analysis and 2) analytical estimation for weak lensing distortion from a large ensemble of galaxy images.
