As a native of Santa Rosa and avid outdoorsman, Ryan has spent much of his free time on the rivers, the wetlands, farmlands and coastal mountain ranges of the Bay Area and greater California. After high school, Ryan attended the University of California – Davis where he earned both his undergraduate degree and a Masters of Science in Soils and Biogeochemistry. His thesis work focused on mapping and modeling regolith thickness for the western slope of the Sierra Nevadas of California, and linking thickness to water storage and its effects on forest susceptibility to drought-induced mortality. As Pepperwood’s Research Technician, Ryan is helping to lay the groundwork for Pepperwood’s rapidly expanding wireless meteorological and soil sensor network, and is in charge of data management and acquisition from these systems.
