SANGHOON KWAK (곽상훈)
I am a (tenure-track) Assistant Professor at the Department of Mathematics Education at Seoul National University.
Previously, I was a CMC fellow (Hyo Chul Myung Assistant Professor) at June E Huh Center for Mathematical Challenges in KIAS.
I completed my Ph.D. in Mathematics in 2024 at the University of Utah. My advisors were Mladen Bestvina and Priyam Patel.
I obtained my Bachelor's degree in Mathematics in 2019 from KAIST, under advisory of Hyungryul Harry Baik.
