Research Interests
My research focuses on the behavior of metals in magmatic-hydrothermal systems. My approach is to combine field and experimental studies to identify the mechanisms that are important for concentrating metals and controlling mineralization, then quantify these processes to develop ore deposit models and exploration strategies.
