Patrick Sweeney

Patrick Sweeney joined the Peabody Museum as Collections Manager in the Division of Botany in 2008. In addition to managing the Peabody's botanical collections, Patrick's interests include flowering plant systematics and evolution, North American floristics, and biodiversity informatics.

Ph.D., 2008, Department of Biology, University of Missouri–Saint Louis

M.S., 1999, Department of Botany, University of Georgia

B.S., 1994, Department of Biology, Georgia Southern University

His more recent taxonomic and systematic research focuses on Viburnum (Adoxaceae) and the mangosteens (the genus Garcinia, Clusiaceae). He is also interested in the North American flora and has conducted survey and inventory work in the eastern and central United States. Additionally, he has been heavily involved in several herbarium digitization projects, including the New England Vascular Plants, Lichen/Bryophyte, and the Pteridophyte Collections Consortium TCNs, among others.
