Dr. Alan Whittington
E.B. Branson Professor of Geological Sciences and Department Chair
Current research topics include:
• rheology and thermodynamics of liquids and multiphase magmas on Earth, other planets, and in circumstellar dust shells
• volcanic eruptions: lava flow emplacement and effusive-explosive transitions
• thermal properties of crustal rocks: lab measurements, 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 a range of topics in igneous and metamorphic petrology, experimental petrology and volcanology. Research field areas to date include the western Himalaya, Antarctica, Brazil, northern Ontario, the Rocky Mountains, Guatemala, Hawai'i and Réunion.
• Viscometry lab: 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
• Calorimetry lab: we have two Differential Scanning Calorimeters (Netzsch DSC 404 Pegasus and Perkin Elmer DSC 8500), and we can measure heat capacity and enthalpies to 1500°C
• Thermal diffusivity: Laser-Flash Analysis (LFA) 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
• Current lab members: Stuart Kenderes (PhD), Jesse Merriman (PhD), Aaron Morrison (PhD), Derick Roy (senior thesis), Arianna Soldati (PhD)
• Lab alumni: 13 undergraduates (8 senior theses), 8 MS, and 3 PhD. Most went into industry or continued on to higher degrees. Four lab alumni are now faculty members, and I encourage PhD students to take a graduate Minor in College Teaching.
