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 and scandium.

I also have a general interest in the techniques used in magmatic-hydrothermal experiments. Some of these techniques include cold-seal pressure vessels, evacuated silica tubes, gas-mixing furnaces, internally heated pressure vessels, as well as various experimental controls including fugacity control. On a broad level I am also interested in the application of these techniques to fields other than economic geology, such as volcanology, petrology, and mineralogy.
