Stephanie S. Jarvis, MSc

Stephanie Jarvis is an interdisciplinary mycologist and executive cultivator with over 20 years of leadership in solid-state fermentation, fungal biotechnology, and ecological restoration. With a Master of Science in Ecology, Evolution, and Conservation Biology from San Francisco State University, her groundbreaking thesis on the Lycoperdaceae of California included statewide fungal surveys, DNA sequencing, and the discovery of two new species.

Stephanie has since built a career at the intersection of applied science and regenerative agriculture. She is the founder of Pacific Truffle Growers, where she leads orchard restoration, truffle DNA diagnostics, and mycorrhizal cultivation strategies across the U.S.A. Her dual background in taxonomy and field management has made her a trusted consultant for landowners, mushroom farms, and food innovators alike. Additionally, Ms. Jarvis is the Director of Mycology for the largest functional mushroom farm in North America, M2 Ingredients, where she spearheads many R&D projects to improve the efficacy of the functional mushroom industry.

A recognized authority in functional mushroom cultivation, Stephanie has developed substrate efficiency protocols for species like Hericium erinaceus, Cordyceps militaris, and Ganoderma lucidum, leveraging qPCR and NGS to validate species purity and optimize biological efficiency. Her passion for sustainable systems includes pioneering the reuse of wine industry byproducts for Shiitake and Oyster mushroom cultivation.

Beyond the lab and field, Stephanie is an award-winning educator, keynote speaker, and lifelong mentor. She has led university biology clubs, authored public-facing educational programs, and served as an advisor to the North American Truffle Growers Association. Certified as both an arborist and fermentation specialist, she brings rare fluency in science, soil, and storytelling — cultivating not only fungi but futures.
