Benjamin Lee Professorship
Overview Plus Minus
Benjamin Lee distinguished professorship is created in honor of Korea's foremost theoretical physicist, late Benjamin Lee, who had a distinguished career in particle physics theory. The program is intended to invite a theoretical physicist of international prominence to stay at APCTP for an extended period. The visit is expected to provide opportunities for the domestic scientists and graduate students to interact with an world-caliber theoretical physicist in their fields of study. The Benjamin Lee professor may give lecture sessions and/or organize small workshops built around the theme of his/her research during the stay.
