معرفی
ChangHoon Hahn is an Assistant Professor in the Department of Astronomy and an Assistant Astronomer at Steward Observatory, affiliated with the University of Arizona. His research focuses on applying machine learning to galaxy surveys to address fundamental questions in cosmology, such as dark energy's nature, neutrino mass constraints, and the interplay between dark matter environments and galaxy evolution. He leads the Dark Energy Spectroscopic Instrument (DESI) survey and the Prime Focus Spectrograph (PFS) Cosmology Survey, while also spearheading collaborations in cosmological simulations and statistical tool development.
He is part of the Steward Theory, Data and Computation Group, driving interdisciplinary efforts between observations, simulations, and advanced computational methods. His work bridges large-scale structure cosmology and galaxy evolution, emphasizing innovative data-driven approaches to unlock astronomical datasets' potential.
While no specific awards or funded grants are listed, his leadership roles in major surveys and collaborations highlight his significant contributions to the field. He enjoys hiking, cooking, and tennis, and also explores causal inference and climate policy analysis in his personal time.
