I am a postdoctoral associate working in Prof. Alberto Bolatto's research group. I am broadly interested in the physics of star formation, interstellar medium, galactic nuclei, and their roles in driving galaxy evolution. My current research focuses on molecular gas and its star formation efficiencies across nearby galaxies, using observations from Atacama Large Millimeter/submillimeter Array (ALMA), James Webb Space Telescope (JWST), and the Green Bank Telescope (GBT). Previously, I received my Ph.D. in Physics from University of California San Diego. I also received a M.S. degree in Physics and a B.S. degree in Electrical Engineering from National Taiwan University. For more information, please check out my personal website.
