Understanding the evolution and timing of ice sheet geometry and extent in Iceland during the Last Glacial Maximum LGM and subsequent deglaciation has long been the focus of much active research. Results indicate that the ice margin retreated to positions inside the present-day coastline between The timing of ice margin retreat in northern Iceland is concurrent with periods of rapid glacier recession in both Greenland and Norway, suggesting a common driver of deglaciation in the circum-North Atlantic region that likely involved perturbations in ocean circulation and attendant changes in temperature. The improved terrestrial chronology of glacial thinning, retreat, and ice stream activity in this region will inform future glaciological modeling studies in Iceland. Master's Theses and Capstones.

I apply the tools of geochronology and geochemistry to study the formation of soils and surfaces, to measure timing and rates of volcanic processes and tectonic deformation, and to reconstruct paleoclimate. It will also allow the correlation of the effects of regional climatic variations with global climate. Stable cosmogenic nuclides can be used to determine exposure ages of modern surfaces and they can give insights into how long buried materials have resided within about 2 m of a paleo-surface. This method has also revealed extremely low surface erosion rates of limestone plateaux in Southern Germany over the last 10 Ma Chapter 3 of my dissertation. I have utilized this technique to date a soil at Whitewater Hill in order to determine slip rates of the Banning Strand of the San Andreas fault on San Gorgonio Pass Chapter 5 of my dissertation.
