The Department of the History of Science is a lively interdisciplinary community of scholars and students who seek to advance understanding of science, technology, and medicine in their historical and social contexts. Our faculty and students employ diverse approaches—from historical and ethnographic methodologies to those informed by Science and Technology Studies (STS)—to examine the past and present workings of the sciences and technology, the bases of their authority, the ethical and political dimensions of their regulation and applications, and the relationships among them and larger intellectual, cultural, social, and political trends and changes. Faculty and student interests span medieval to contemporary times, from the local to the global. Many of us work on topics that engage contemporary social and political themes and are relevant to policy questions and choices. An intellectual openness to new approaches and domains of study characterizes our work.
