Faculty and Research

The Global Human Development program draws on faculty with extensive knowledge of economics, political science, sociology, anthropology, international relations, and development. In addition, GHD’s faculty bring extensive experience in the field of international development, with expertise from the private, public, and nonprofit sectors. Faculty members teach core and elective courses as well as advise students in GHD’s designated concentration areas.

"GHD faculty support is second to no other graduate program. Between our small class sizes and constant willingness to meet during office hours or over a coffee, I can personally attest to each faculty member's desire and ability to help me learn and develop professionally over the course of the program."
