SANGHOON KWAK (곽상훈)

I am currently a CMC fellow (Hyo Chul Myung Assistant Professor) at the June E Huh Center for Mathematical Challenges in KIAS.

I completed my Ph.D. in Mathematics at University of Utah. My advisors were Mladen Bestvina and Priyam Patel.
I obtained my Bachelor's degree in Mathematics from KAIST, under advisory of Hyungryul Harry Baik.
