Vita

Research:

Current research topics include:

• rheology and thermodynamics of lavas on Earth and other planets

• thermal properties of crustal rocks, and thermal / strength profiles of the crust through time

I regard the combination of field- and lab-based studies as essential to much research in the geosciences. Doing both enhances my understanding of geological processes and increases my enjoyment of both kinds of work. My research has spanned crustal melting and granitic plutonism in orogenic belts; shallow basaltic sheet emplacement in sedimentary basins; measurements of the viscosity, other physical properties and thermodynamics of silicate liquids; metamorphic petrology in high-grade metamorphic rocks. Research field areas to date include the western Himalaya, Antarctica, the Rocky Mountains, Brazil and Guatemala.

Facilities:

• Viscometry: we have both concentric cylinder and parallel plate viscometers to measure viscosity at high and low temperatures, from ~1 to 105 Pas and from ~108 to 1013 Pas, and a high temperature (1700°C) muffle furnace for sample synthesis
• Differential Scanning Calorimetry: we have a new high-temperature Differential Scanning Calorimeter / Drop Calorimeter, capable of enthalpy and heat capacity measurements to 1300°C
• Thermal diffusivity: in collaboration with Anne Hofmeister, at Washington University (St. Louis)
• Infrared spectroscopy of circumstellar dust shells: in collaboration with Angela Speck, MU Physics and Astronomy
