Brief professional biography:


Dr. Anna L. Jacobsen completed her undergraduate studies as a Regents' Scholar at Pepperdine University in Malibu, CA where she conducted research on chaparral shrub anatomy and hydraulic function in the laboratory of Dr. Stephen D. Davis and was awarded a Pennsylvania State James A. Finnegan Fellowship in 2001.  She graduated from Pepperdine University in 2003 with a B. S. Biology with honors.  In 2003 she was selected as a participant in the Fulbright U.S. Student Program and she spent 2004 living and conducting research in South Africa at Stellenbosch University as a Fulbright Scholar.  Upon returning to the States, she entered graduate school in the Department of Plant Biology at Michigan State University, East Lansing, MI in the laboratory of Dr. Frank W. Ewers.  Her graduate studies were supported by a National Science Foundation Graduate Research Fellowship (NSF-GRF) (2004-2007) and a National Science Foundation Doctoral Dissertation Improvement Grant (NSF-DDIG; Division of Environmental Biology DEB-0710020) (2007-2008).  Dr. Jacobsen completed a dual Ph. D. in Plant Biology and Ecology, Evolutionary Biology, & Behavior (EEBB) in 2008.  She was a post-doctoral researcher on a grant funded by the Andrew W. Mellon Foundation at California State University, Bakersfield (2008-2010).  In 2010, she was hired as an Assistant Professor in the Department of Biology at California State University, Bakersfield where she has developed an active research program investigating plant hydraulic structure-function.  She was awarded a prestigious National Science Foundation CAREER award in 2013 (NSF-CAREER; Division of Integrative Organismal Systems IOS-1252232) (2013-2019) and is a member of the CSUB Center for Research in Excellence in Science and Technology (NSF-HRD CREST 1547784; 2016-2021).  Dr. Jacobsen was promoted to Associate Professor in 2014 and to Professor in 2018.  She has published numerous scholarly articles in her areas of expertise (list of selected publications).



CSUB Biology Club:  Dr. Jacobsen is currently serving as the faculty co-advisor (with Dr. R. Brandon Pratt) to the CSUB Biology Student Club (2015-present).  More information about the club and upcoming events and activities may be found here: Biology Club.  Go Runners!


Recipient of the CSUB Faculty Scholarship and Creativity Award 2018-2019: Dr. Anna Jacobsen was the recipient of the Faculty Scholarship and Creativity Award 2018-2019.  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.  Dr. Jacobsen has also studied key crop plants like grapevine and olive, examining their vascular function in the context of irrigation, productivity, and pathogens.  Dr. Jacobsen has developed and maintained a highly active and successful research program.  She has produced many peer-reviewed publications, been funded by outside agencies, and provided numerous opportunities for student involvement in and exposure to scientific research.
