I have 18 years of experience, and specialize in the field of geochemistry with specific knowledge in the areas of stable isotopes, ore deposits and contaminant transport processes. I have published on such topics as the transport of crustal fluids, the development of stable and radiogenic isotope techniques for mineral exploration and mixing processes in groundwaters in aquifers. I have an active research program that applies stable isotopic techniques to understand fluid transport processes in the earth’s crust.
