Wegmann's Wordle — Created from publication titles as of January 2012
My research interests include the intersections of the fields of geomorphology, active tectonics,geodynamics, paleoseimology, paleoclimatology, and biogeomorphology. I approach research problems in a field-based, process-oriented, multidisciplinary manner.
My current research addresses questions such as:
How do landscapes respond to tectonic and climatic forcing, and are there distinct topographic, erosional, stratigraphic, and bio-genetic signatures of these forces?
How constant in space and time is strain accumulation and release across convergent margins? How do long-term geologic and geomorphic estimates compare to short-term geodetic measurements?
What conspiracy of geologic, seismologic, and climatic factors is important to the initiation of large, deep-seated bedrock landslides?
High-elevation, low relief surfaces are common on continents. These intercontinental plateaus influence river networks, climate, and the migration of plants and animals. How these plateaus form is not clear. We are studying the geodynamic processes responsible for surface uplift in the Hangay in central Mongolia to better understand the origin of high topography in continental interiors.

Landslide dammed Lakes - paleoseismic archives
In July of 2009, Joe Kasperski (NCSU senior geology major) spent a week collecting samples of rooted snags from the bottom of the Upper and Lower Greenwater Lakes for radiocarbon dating. Joe is working on correlating the timing of landslide movement to known regional paleoseismic events, in order to determine if the landslide damming these two lakes might have been seismically-triggered.
