The Princeton Society of Fellows in the Liberal Arts, a group of postdoctoral and faculty fellows, is dedicated to promoting innovative interdisciplinary approaches to scholarship and teaching. Each year the Society chooses a new cohort of Cotsen Fellows, recent recipients of the Ph.D. in the humanities and selected social and natural sciences, who are appointed for three-year terms to pursue research and to teach half-time in a home department or program at the University. The Cotsen fellowships were established in 1999 through the generosity of Charter Trustee Lloyd E. Cotsen, an alumnus who has long been a devoted supporter of Princeton.
