Dr. Anna L. Jacobsen is a Professor of Biology at California State University, Bakersfield. Her core research focuses on plant vascular structure and function. This is an integrative and interdisciplinary field requiring her to be an expert in microscopy, plant anatomy, evolution, and plant physiology. She has used a comparative community approach to test long standing questions in plant evolution and ecology, with a focus on California native plants and mediterranean-type ecosystems. Dr. Jacobsen has also studied key crop plants like grapevine and olive, examining their vascular function in the context of irrigation, productivity, and pathogens.
