My research and
teaching interests are in process
geomorphology and landscape evolution. I am specifically
interested in using fieldwork, geochronology, and GIS to
investigate landscape responses to tectonics and climate change
and the landscape evolution of the Colorado Plateau.
I am originally from rural Minnesota, made a pilgrimage
to the Southwest for graduate study, and am now lucky
enough to be employed here at Utah State. I am
married to Carol Dehler, also a professor here in
Geology, and we have a son, Zane.
How do river terraces
form and do they correlate across the region?
How do drainage position and geometry control alluvial stratigraphy?
What roles do climate change versus upstream-migrating baselevel controls have?
Geoarchaeology of the Colorado Plateau
is the Holocene stratigraphy of the Colorado River?
Can OSL be used to date rock art and other archaeological features?

HEY! I usually need grad students to come to Utah, hike, raft and ski, and work on projects in the beautiful Southwest! EMAIL ME!
fieldwork, OSL geochronology, and GIS terrain analysis. The facilities and
collaborators here at USU for geomorphic
studies are awesome.
Check out our Luminescence Laboratory and the Watershed Department.
potential graduate research themes:
1) Rates, processes and climate controls on escarpment retreat
2) Using river terraces and topopgraphy to quantify incision and active deformation in the Colorado Plateau
