Associate Professor

Teaching and Research

I am a field-based geologist with research interests in large-scale tectonic problems that are addressed through collaborative research and focused, process-related studies. In addition to structural geology and petrology, one of my main tools is radiometric dating of rocks and minerals to quantify absolute timing of events and rates of processes. I direct the 40Ar/39Ar geochronology laboratory here at UVM. My students and I integrate observations over a large range of scales from microstructures to regional geological and geophysical data sets, and employ a suite of methodologies to evaluate P-T-t-D histories and the 4D evolution of rocks and regions.

I teach courses in geochronology, petrology, microstructural analysis and tectonics. In the classroom and in practice, my students and I integrate analytical data with observations made at microscopic to continental scales to try and understand how rocks and regions evolve in space and time and the tectonic processes that shape them.
