Recently I have been investigating the Paleozoic and Mesozoic tectonic evolution of Northern Alaska and the Arctic region in general. I enjoy exploring the geology of the remote northern mountain belts. In the last few summers I have been doing field work along the rivers that drain Alaska’s Brooks Range. With my students and collaborators, we map and sample for geochronology, thermochronology and paleothermometry in order to unravel the history of the assembly of Northern Alaska. I have also lead projects on the structure and evolution of the Appalachian fold-and-thrust-belt and the Appalachian basin. I am starting a new project in collaboration with Stockholm University and the USGS to study the evolution of the Koyukuk basin, located south of the Brooks Range.
