Projects and/or Research Interests

In my current position at DGGS I manage a variety of Quaternary geologic mapping and geologic hazards projects. My focus is on areas where geologic mapping and geologic hazards investigations are needed to help with planning and resource development decisions. Mapping projects occur in areas where available map products are either lacking or are not at a detailed enough scale.

My main research interests are in Quaternary geology, geomorphology, and engineering geology. I have experience doing detailed surficial geologic mapping that involves combining field investigations with remote sensing techniques such as air photo and lidar interpretation, and my work requires extensive use of GIS. My mapping projects with the State of Alaska have included: 1) areas in the Northern Arctic foothills; 2) near Kivalina; and 3) along the Alaska Highway between Delta Junction and Canada where my work included creating interpretive permafrost and derivative engineering geology maps.

I am currently working on a surficial geologic map for an area in the northern Talkeetna Mountains and am conducting geologic hazards investigations, in collaboration with faculty and graduate students from the University of Alaska Fairbanks, of frozen debris lobes along road corridors in the southern Brooks Range. Other projects include a dendrogeomorphology study of a landslide near Northway with faculty and a student from St. Lawrence University, an interpretive lidar atlas along the road corridor between Livengood and Valdez and a geologic guidebook along the Tok cutoff between Slana and Tok.
