Jon will be joining Jenny Druhan’s lab for his PhD in Fall 2019, and his successful proposal centers on the use of mid-mass stable isotope ratios to parse between weathering and vegetation influences on solutes in the Critical Zone. He will primarily use the unique instrumentation available at the Eel River Critical Zone Observatory and related catchments now part of the French Critical Zone Network OZCAR. Jon is currently completing his MS at the University of New Mexico, and will spend summer 2019 on a USGS internship. Welcome and congratulations Jon!
