Yao-Yuan MaoView profile
Assistant Professor
Yao-Yuan Mao is an Assistant Professor of Physics and Astronomy at the University of Utah since July 2022. Their research delves into the mysteries of dark matter and galaxy formation, focusing on low-mass galaxies and their connection to dark matter halos through astronomical surveys and numerical simulations. Education: Ph.D. in Physics, Stanford University (2016) B.S. in Physics, National Taiwan University (2009) Research Interests: Yao-Yuan Mao's work addresses fundamental questions about dark matter, galaxy formation physics, and the uniqueness of the Milky Way. By studying low-mass galaxies in the nearby universe, they model the relationship between galaxies and their host dark matter halos to uncover the underlying cosmic structures. Their research spans cosmology and extragalactic astronomy , astroparticle physics , and astronomical instrumentation . Scientific Collaborations & Leadership: Co-leader of the SAGA Survey , a galaxy redshift survey characterizing satellite systems around Milky Way analogs. Active in the Rubin Observatory science community. Co-convener of the LSST DESC Science Release and Validation Working Group . Former co-lead of the DESC Dark Matter Working Group and Data Access Team. Served as Collaboration Council Chair and Hack/Sprint Coordinator for LSST DESC. Credited with Builder Status by DESC in 2019. Grants & Funding: HST Cycle 31 Proposal 17484: "BEYOND PANDAS: Two Extremely Faint Candidate Satellites of M33 Identified in Diffuse Light" (2024-2025) HST Cycle 31 Proposal 17501: "LONE LION OR PART OF A PRIDE: PROPER MOTION AND ORBIT OF LEO P" (2024-2027) "Discovery of Six Isolated Ultra-Faint Dwarf Galaxy Candidates in the Local Group" (2024-2027) NASA Hubble Fellowship Program: "Reconstructing the Assembly History of Andromeda" (2023-2025) Advocacy & Service: Yao-Yuan is committed to inclusion and equity in academia. They are the current maintainer of the Astronomy and Astrophysics Outlist and serve on the AAS Committee for Sexual-Orientation and Gender Minorities in Astronomy (SGMA) .
