The College of Letters & Science is made up of four distinct divisions: the Division of Humanities and Fine Arts; the Division of Mathematical, Life, and Physical Sciences; the Division of Social Sciences and the Division of Undergraduate Education. Each of our divisions is led by a senior administrator.
