About Me

My research has concentrated on the plumbing systems of silicic calderas. Caldera-forming eruptions are some of the most devastating events that occur on Earth, and understanding the processes that produce them is essential to providing better forecasts of the size of the next eruption at restless calderas. These volcanoes also concentrate valuable metals in their plumbing systems, producing economically important ore deposits. My main focus has been on the magmatic processes that occur prior to eruption at silicic calderas. Using the geochemistry and petrology of the deposits of past eruptions, I have studied the timescales of these processes, and attempted to determine whether the processes that drive the largest, caldera-forming eruptions differ from those that drive minor, effusive activity at the same volcano.
