Invited plenary talks at Strings conferences

"Strings" is the most important annual conference in string theory and has been held every year since 1995. Ooguri has given invited plenary talks at the following Strings Conferences.

Ooguri was an organizers of Strings '98, Strings 2003, and Strings 2018 (chair).
