My research focuses on using geochemistry and sulfur isotopes (δ34S) to understand the formation of hydrothermal mineral deposits. I apply observations made at the scale of individual mineral grains to understand temporal variations in the source of metals, and changes in the chemical and physical composition of mineralizing fluids during mineral deposit formation. I couple these mineral-scale observations with more traditional bulk-rock geochemical analysis, alteration mineralogy and reflected/transmitted petrography to understand the processes that form economically viable ore deposits. I have experience working with volcanogenic massive sulfide (VMS) deposits and their modern analogues seafloor massive sulfide (SMS) deposits.
