From September 2021, I will be an associate professor at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU) at the University of Tokyo in Japan. I welcome students and postdocs to work with me on cosmology related projects. Please reach out if you are interested!

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.
