My research focuses on the large scale structures of our universe –– dark matter, halos, filaments, and voids. I aim to elucidate fundamental physics, such as the nature of dark energy and neutrino mass, using cosmological observations of the cosmic microwave background and galaxies together with state-of-the-art numerical simulations. I am a member of the Rubin Observatory Legacy Survey of Space and Time (LSST) Dark Energy Science Collaboration (DESC), Simons Observatory, and CMB-S4. I welcome students and postdocs to work with me. Please reach out if you are interested!
