Stephen Harris

Professor Stephen Harris is an Associate Professor in Plant Sciences at the University of Oxford, affiliated with Christ Church. He serves as the Druce Curator of the Oxford University Herbaria, overseeing the curation of botanical specimens. His research focuses on evolutionary and conservation biology using molecular markers, hybridization, polyploidy, and the impacts of human-mediated plant movements. He also explores the historical dimensions of botany, including the use of herbarium specimens for DNA analysis and the history of botanical expeditions like Sibthorp's Flora Graeca. His work bridges traditional botanical studies with modern genetic techniques, contributing to both academic and conservation efforts.

His academic roles include curating the Department of Biology's collections at two Oxford locations (Mansfield Road and South Parks Road). His research extends to endangered species conservation, particularly in Chilean and Amazonian ecosystems, and the role of fragmented habitats in species survival. Harris has also explored the cultural and economic dimensions of botany in historical contexts, such as the transnational exchange of botanical knowledge during the 18th and 19th centuries. His interdisciplinary approach integrates historical analysis, molecular biology, and conservation strategies.

Notable projects include studies on hybrid speciation in Oxford ragwort, the genetic impacts of selective logging on Amazonian trees, and the preservation of botanical illustrations from early expeditions. His publications span topics from seed biology to the legacy of historical botanists like William Dampier and Ferdinand Bauer. Despite no listed awards or students, his contributions to herbarium curation and historical botanical research are significant. His work underscores the interplay between historical documentation and modern conservation challenges.
