RESEARCH
My research bridges the fields of
low-temperature stable Isotope geochemistry,
environment, energy,
water resources and ecology. I primarily use stable isotopes
of C, O and H as natural tracers to understand
modern environmental processes and to interpret past
environments. Recent projects include:
-
Acquisition
of Instrumentation for compound specific isotope analysis at the University of
University of Wyoming (Co-PI with D.G. Williams, C.M.del Rio, E. Pendall,
M.T. Clementz). Funded by NSF $467,608; 2009-2011
-
-
-
-
-
- Volcanic degassing
in Yellowstone National Park: An un-tapped research opportunity for studying
effects of elevated CO2 on coniferous forest (PI with
D.G. Williams). Funded
by faculty-grant-in-aid University of Wyoming Research Office $7,500; 2006-2007.
