Over the past thirty years, Schiebinger's work has been devoted to teasing apart three analytically distinct but interlocking pieces of the gender and science puzzle: the history of women's participation in science; gender in the structure of scientific institutions; and the gendering of human knowledge. Schiebinger's work in the eighteenth century investigates colonial science in the Atlantic World. In particular she explores medical experimentation with slave populations in the Caribbean. Her project reconceptualizes research in four areas: first and foremost knowledge of African contributions to early modern science; the historiography of race in science; the history of human experimentation; and the role of science in the eighteenth-century Atlantic world.
