Lauren Parker

Lauren Parker joined the USDA California Climate Hub in August 2018 following a position as a postdoctoral fellow at the University of Idaho, where she also earned her PhD in 2017. Dr. Parker is a geographer by training, with a focus on agricultural climatology and perennial crop systems. Lauren comes to the California Climate Hub with a background in applied climatology, phenology and bioclimatic niche modeling, spatial analysis, and education and curriculum development. Her dissertation focused on projecting shifts in the geographic distribution and reproductive phenology of almonds under future climate scenarios through the development and use of phenology-based crop suitability models. Dr. Parker’s recent work has examined topics including extreme heat, frost exposure, shifts in agroclimate metrics, and opportunities and barriers to agricultural adaptation in California. Lauren has applied her background as an educator to support the production of science communications and translational products, outreach and education projects, and in service as an ad hoc technical advisor for Hub collaborators developing climate-focused curriculum.
