Mathematical Olympiads

I’ve been involved in selecting and educating highly gifted students in Korea to compete in International Mathematical Olympiad (IMO). For 2011-2012 and 2017-2018, I was/have been an executive member of the Board of Trustees, Korean Mathematical Society in charge of the Korean Mathematical Olympiad (KMO).

KAIST Math Problem of the Week

I’ve been managing the KAIST Math Problem of the Week (2008-2012, 2014-), jointly with Prof. Ji Oon Lee.


Until the end of November 2018, I had been one of the founding editors of the Horizon, a math and science blog run by KIAS.
