Current research interests

I am interested in a wide variety of igneous processes. My current focus is on the kinetics of reaction between silicate and oxide minerals and silicate melts, the petrology of the upper mantle in the Quaternary West Eifel volcanic region in Germany; the dynamics of magmatic systems and the synthesis and characterization of new high pressure minerals.

Equipment available:

• 2 piston cylinder presses (to 4 GPa and 2000 °C)
• 1 atmosphere gas mixing oven (temperatures to 1600 °C and various oxygen fugacities)
• Hydrothermal apparatus (to 0.3 GPa and 850°C)
• Ultrahigh T furnace (to 1750°C)
