Biography, Education and Training

Dr. Broome is an Assistant Adjunct Professor at the University of California, Santa Cruz in the Environmental Studies Department, and affiliated with the campus Center for Agroecology.  She conducts research into berry and grape plant health. Current projects include:

·       California Council of Science and Technology (CCST) author for a study on Fumigant Use in California and an Assessment of Available Alternatives https://ccst.us/reports/fumigant-use-in-california/

·       California Department of Food and Agriculture’s Biologically Integrated Farming Systems (BIFS) for strawberry grant 2025-2029 CDFA - OEFI - OPCA - Biologically Integrated Farming Awards

·       Project manager for UC Santa Cruz Center for Agroecology organic viticulture initiative. Center for Agroecology: Growing sustainable food systems

She very recently retired from being Senior Research Manager of the Global Plant Health Department and Scientist at Driscoll’s Inc. based at the Global R&D campus in Watsonville, CA. She worked with Driscoll’s for 13 years and provided strategic planning, staff direction and development, and budgetary oversight ($1.3 million annual budget) for a team of 7 scientists. In addition, she helped coordinate cross departmental and geographical research and extension with breeding, molecular biology, applied research, and plant propagation nurseries globally.  She and her departmental scientists provided plant pathogen diagnostics and conducted research to generate management recommendations. They also assisted plant nurseries with design of testing and handling programs to ensure clean planting stock. She worked with host resistance pathologists and berry breeders to characterize Driscoll’s proprietary germplasm in terms of susceptibility to important pathogens. Driscoll’s Inc. is the leading producer of fresh berries (strawberry, raspberry, blackberry and blueberry) in markets across the globe with nursery and fruit production operations in more than 20 countries.

She and colleagues have been conducting, funding and coordinating research on pre-plant soil and plant health treatments such as using anaerobic soil disinfestation (ASD), organic amendments and soil solarization, mobile steam treatments, and crop rotations relevant to organic berry crop production, as well as chemical fungicides and fumigant alternatives to methyl bromide.  Jenny has also worked in biological, chemical, and integrated control of above ground plant pathogens including work using weather-driven infection risk models to time fungicide applications for Botrytis gray mold and powdery mildew pathogens, and use of novel technologies such as nighttime UVC (254 nm at 200 j/m2) applications among many other projects.  She led the global nursery clean stock program which included developing, deploying and quality assurance for molecular and classical pathogen testing of asymptomatic and symptomatic planting stock for viruses, bacteria, phytoplasma, fungal and oomycete pathogens that are found in clonally propagated berry crops.  Her team designed, documented, and audited against global standards for whole nursery system clean stock programs for the four (strawberry, raspberry, blackberry, blueberry) berry crops including critical point and hazard assessments.  

Earlier she worked with the University of California in research and extension positions for 13 years, including serving as Associate Director of the statewide ANR UC Sustainable Agriculture Research and Education Program, and serving as Area Plant Pathologist Academic Coordinator in the Sacramento Valley. She brings regulatory experience; having spent three years with the Department of Pesticide Regulation as a senior environmental research scientist and served for 10 years on DPR’s Pest Management Advisory Committee.  She has authored 26 peer reviewed publications, served on US national scientific advisory and review committees, and administered granting programs.  Dr. Broome received her doctorate and M.S in plant pathology from UC Davis, and an undergraduate degree in biology from Swarthmore College.
