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 climate change and
the uplift and erosion 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.
The Arroyo Problem in
How do thresholds of drainage position and geometry control alluvial stratigraphy?
What roles do climate change and sediment supply have in the arroyo cycle?
Geoarchaeology of the Colorado Plateau
is the Holocene stratigraphy of the Colorado River?
What is the geomorphic context of archaeological sites in Grand Canyon?
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!
Most projects are
fieldwork-based but include OSL geochronology and GIS.
The facilities and collaborators here at USU for geomorphic studies are awesome.
Check out our Luminescence Laboratory, the Watershed Department, and the Utah Water Research Laboratory.
potential graduate research themes:
How climate change controls sediment supply, transport,
and storage in desert catchments
2) River integration and canyon cutting in the Interior West
Rates, processes and controls on incision and escarptment
retreat in the Colorado Plateau
