Previously,…
Postdoctral fellow at
Dept. of Combinatorics and OptimizationUniversity of Waterloo (2007/1-2007/12)
and a visiting assistant professor (~Postdoc) at
School of MathematicsGeorgia Institute of Technology (2005/8-2006/12).
I received my Ph.D. from Princeton University in 2005. My Ph.D. advisor was Paul Seymour.

I received my B.S. from KAIST in 1998.

Curriculum Vitae(Last update: March 4, 2011)

I am organizing the KAIST Discrete Math Seminar. I strongly encourage everyone including students interested in discrete mathematics to attend this seminar and subscribe the mailing list.

I’m currently managing KAIST Math Problem of the Week.

On October 27-29, 2011, the 5th workshop on Graph Classes, Optimization, and Width Parameters (GROW 2011) was held at KAIST in Korea. More information will be posted later. This is a continuation of the series of meetings: Barcelona 2001,  Prague 2005, Eugene 2007, and Bergen 2009.

As of January 2011, I am appointed as one of the editors of Journal of the Korean Mathematical Society. I am also serving as an executive member of the Board of Trustees (사업이사), Korean Mathematical Society (대한수학회).

I was in the program committee of the 37th International Workshop on Graph-Theoretic Concepts in Computer Science (WG2011) to be held in Czech Republic, June 21-23, 2011.

I became a joint professor at Department of Computer Science, KAIST on September 2010.

Seog-Jin Kim and I organized a special session on graph theory at Korean Mathematical Society Spring Meeting, April 2010.

I co-organized the Winter School on Algorithms and Combinatorics, January 13-16, 2010 in Korea.

I am in the Program Committee of the 7th Annual Conference on Theory and Applications of Models of Computation (TAMC 2010), Prague , Czech Republic, June 7-11, 2010.

I co-organized the 2009 Combinatorics Workshop, August 20-21, 2009 at KAIST.

I was in the Program Committee for the 2nd Canadian Discrete and Algorithmic Mathematics Conference (CanaDAM 2009), May 25-28, 2009 at Montréal, Canada.

I was in the Program Committee of the 35th International Workshop on Graph-Theoretic Concepts in Computer Science (WG2009), June 24-26, 2009 at Montpellier, France.
