Projects and/or Research Interests

In my current position I am a manager of the DGGS Surficial Geologic Mapping and Corridor Studies Program, where I manage projects involving surficial-geologic mapping and evaluation of potential geologic hazards. My goal is to better understand Alaska's surficial geologic material resources and potential geologic hazards in areas where information is needed to make well-informed, scientific-based decisions related to land use and resource management. Much of this work involves producing geologic- and geohazard-based maps and associated reports by combining the evaluation of remotely-sensed data with field-based observations and geospatial analysis.

My current projects include:

  • Evaluating geologic hazards and the distribution and character of geologic materials on Alaska's North Slope, in the eastern Yukon-Tanana Uplands and along the Yukon River near the Dalton Highway crossing
  • Evaluating potential landslide hazards in regions of unstable slopes near Sitka, Alaska, and selected other sites along infrastructure corridors
