Bruce G. Baldwin W. L. Jepson Professor and Curator, Jepson Herbarium and Integrative Biology 1001 Valley Life Sciences Bldg., #2465 Berkeley, CA 94720-2465 (510)643-7008 bbaldwin@berkeley.edu The Baldwin Lab

Dr. Bruce Baldwin is the Curator of the Jepson Herbarium and a Professor in the Department of Integrative Biology, where he teaches vascular plant systematics and biosystematics. A native of central coastal California, he attended Arroyo Grande High School in Arroyo Grande, California. He first became interested in plant diversity through backpacking and exploring in the floristically-rich Santa Lucia and San Rafael Mountains of central western California. He received his B.A. degree in Biological Sciences from U. C. Santa Barbara in 1981. He received his M.S. (1985) and Ph.D. (1989) degrees in Botany from U. C. Davis (with Donald Kyhos) and conducted postdoctoral work at the University of Arizona, Tucson (with Michael Donoghue and Robert Robichaux). He was a member of the Botany faculty at Duke University for two years before moving to Berkeley in 1994.

Baldwin's research program encompasses vascular-plant systematics, floristics, and conservation, with an emphasis on biosystematic and phylogenetic studies. He is particularly interested in systematic questions that address evolutionary processes, historical biogeography, and relationships of California plants. His recent research on the Compositae has involved testing of hypotheses concerning speciation, chromosomal and morphological evolution, ecological shifts, dispersal events, and the importance of hybridization during diversification. Laboratory techniques used in his research include DNA sequencing and cytogenetic and morphological analyses.

Baldwin serves as convening editor of The Jepson Flora Project, an initiative to produce new editions of The Jepson Manual: Higher Plants of California, regional manuals of California plants, and the Online Interchange for California Floristics, among other goals. He edited the recently published Jepson Desert Manual, and co-edited (with Sherwin Carlquist and Gerald Carr) and co-authored Tarweed & Silverswords: Evolution of the Madiinae (Asteraceae), published by the Missouri Botanical Garden Press, St. Louis (2003). He also has been involved in floristic efforts outside the Jepson Flora Project (e.g., Flora of North America, Familes and Genera of Vascular Plants).
