Ore Deposits: My research interests are focused on the application of experimental geology to the formation of ore deposits. I perform experiments in cold-seal pressure vessels and evacuated silica tubes to characterize the behavior of metals in magmatic systems. The metals I am interested in are commonly referred to as “critical materials”. Critical materials have been defined as elements that are necessary to the production of technology used in modern life, but are difficult to obtain. These metals commonly include, but are not limited to, the rare earth elements, scandium, yttrium, indium, and tellurium. To date my research has focused on two of these elements: indium (the subject of my MS) and scandium (the subject of my PhD). More information on these metals can be found at the Critical Materials Institute and the United States Geological Survey.
Experimental Geology: I have a general interest in magmatic-hydrothermal experimentation, which includes experiments conducted in cold-seal pressure vessels, evacuated silica tubes, gas-mixing furnaces, and internally heated pressure vessels. In addition, I am also interested in the various techniques used to control experimental conditions (pressure, temperature, oxygen fugacity, pH, etc.). On a broad level I am interested in the application of these experiments to fields other than economic geology, such as volcanology, petrology, and mineralogy.
