His main research fields are combinatorics and computational mathematics. His best known contribution to the field is his proof that the Ramsey number R(3,t) has asymptotic order of magnitude t2/log t.[1] He received the Fulkerson Prize in 1997 for his contributions to Ramsey theory.[2]
In 2008, he became president of the National Institute for Mathematical Sciences of South Korea and was also awarded the Kyung-Ahm Prize. He was discharged of the position in 2011 after being accused of having allegedly misappropriated research funds. However, he was found not guilty by prosecution's investigation.[3]
