Congratulate Prof. Sarnak for the Shaw Prize.

I will move to JBNU as of 2021.09.01.

SJR teacher: I truly wish your recovery. Give many thanks to you, and hope to visit you someday after the covid-19 is settled down. Rest in peace SJR teacher.

As of 2025. 09. 01, I am advising one masters' student, and one more master's student soon. Right now, that is it for me, and I do not have any sparing time for more than 2 students. Sorry for that.
From now on (as of 2023. 03.01), if someone wants to study with me either for master or phd, then the students must appeal how much basic math material they know in Algebra, Analysis, and Topology. To be fair, I am thinking of giving a basic written test (because oral test does not exist as a proof), and those who pass the basic exam are welcome to work with me, if any. If cannot pass, then I will not be able to work with you because my research area needs a lot of work, and please find someone else. I am sorry for that. Also, if nobody wants to work with me, then of course, it is fine with me. Some of you might think I am rude or harsh or arrogant, but if you got to know my situation, you will not say like that. Thanks for understanding !
