Jinyoung Park (mathematician)

Jinyoung Park (born 1982) is a South Korean mathematician at the Courant Institute of Mathematical Sciences at New York University working in combinatorics and graph theory. In 2022, she released a preprint, joint with Huy Tuan Pham, containing a proof of the Kahn–Kalai conjecture. Their paper was published in the Journal of the American Mathematical Society in 2024.

Education and career
Park entered Seoul National University in 2001 and received her B.S. in Mathematics Education in 2004. She worked as a mathematics teacher in secondary schools in Seoul from 2005 to 2011. She began her graduate studies at Rutgers University in 2014, where she received her Ph.D. in 2020 under the supervision of Jeff Kahn. Her doctoral work earned the 2022 Dissertation Prize from the Association for Women in Mathematics.

She was a Member of the Institute for Advanced Study from 2020 to 2021. From 2021 to 2022 she was a Szegö Assistant Professor at Stanford University, where her postdoctoral mentor was Jacob Fox. She joined the Courant Institute of Mathematical Sciences at New York University in 2023, where she is currently an assistant professor.

In 2023, Park received the Maryam Mirzakhani New Frontiers Prize for contributions to the resolution of several major conjectures on thresholds and selector processes. In 2024, she received the Dénes König Prize together with her coauthor Huy Tuan Pham.
