About Dr. Stewart G. Wilson
I am a proud graduate of the California public school system, with my journey winding through California public high school, a California community college, a California State University and the University of California. I earned a A.S. from College of the Redwoods and a B.S. in Wildland Soil Science from Humboldt State University. I hold two masters degrees from the University of California-Davis, one in Soils and Biogeochemistry and one in Geography (GIS and modeling). I hold a Ph.D. in Soils and Biogeochemistry from the University of California-Davis. I am a certified associate professional soil scientist, and have worked in viticulture, in consulting, at an agtech startup, in government for USDA-NRCS and in academics.
My research broadly focuses on how soils form and are distributed across the landscape. My emphasis is on how the formation and distribution of soils informs management and the cycling of elements critical to life on earth. I use traditional mineralogical and biogeochemical methods to investigate how soils form and nutrients are cycled, along with geoinformatics, soil data science and machine learning to understand where soils and soil processes exits on earth. My research focuses on how soil formation influences biogeochemistry and soil mineralogy, using machine learning to understand how soil properties are spatially distributed and sustainable management of vineyard soils. When I’m not working, I enjoy hiking with my family, gardening, mountain biking, surfing and snowboarding.
