Research Interests: Understanding crustal processes and fundamental and applied problems using field work, mineralogy, petrology, geochemistry, isotope geochemistry, modeling, and state-of-the-art analytical techniques. Specific projects include: Fe isotope fractionation in magmatic systems; geochemistry and genesis of critical mineral deposits, the origin of color in minerals; early Earth's geochemistry and genesis of BIFs; geochemistry and genesis of hydrothermal sulfide deposits and spatially associated exhalites; evolution of metamorphic rocks and P-T reconstructions; societal-relevant and community-based geoscience
