Dr. Bruce Baldwin is Curator Emeritus of the Jepson Herbarium and Professor Emeritus in the Department of Integrative Biology, where he taught vascular plant systematics, biosystematics, and plant and fungal biology in introductory biology. 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 Range and San Rafael Mountains of central 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 the late 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 Californian and Hawaiian plants, especially of the sunflower family, Compositae. 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.
