Education and/or Training
Ph.D. Candidate, 2009-2014, Montana State University
M.S. Geology, 2006, Humboldt State University
B.S. Geology, 2001, University of Montana
Professional Geologist No. PG-3950, Wyoming
Projects and/or Research Interests
Mort manages the State of Alaska Division of Geological & Geophysical Surveys Landslide Hazards Program responsible for mapping and assessing landslides throughout Alaska. Mort's role as the manager is dedicated to understanding and quantifying landslide hazards and improving geologic hazard communication and coordination with other agencies and communities.
Mort's present research interests involve an integration of geomorphic processes, Quaternary stratigraphy, engineering geology, and remote sensing to assess and characterize landslide attributes and evolution.
