Currently funded projects:
Metamorphic fluid evolution and rock rheology. Collaborative with Jan Tullis and Adrian Brearley. This project links field-based and experimental studies to examine the effect of changing metamorphic fluid composition on rock rheology. We are focused primarily on the role of CO2, which appears to strengthen quartz in the dislocation creep regime, and is associated with embrittlement in natural graphitic schist exposures (Selverstone, 2005). Papers coming soon....
Pending proposals:
Scales and mechanisms of fluid migration and equilibration during the subduction cycle. Joint with Zach Sharp and Jaime Barnes. Submitted 12/07.
What is the strength of low-angle normal faults? Collaborative with Gary Axen at New Mexico Tech. Submitted 12/07.
Some previously funded projects:
Mantle and crustal xenoliths of the Puerco Necks, New Mexico: Constraints on lithospheric evolution at the transition between the Colorado Plateau and the Rio Grande Rift. Joint with Zach Sharp and Adrian Brearley, along with students George Perkins, Caitlin Callahan, Courtney Porreca, Kym Samuels, and Erik Jung.

Tectonic and metamorphic implications of high chlorine contents in serpentinites. Zach Sharp was lead PI, and Adrian Brearley and I were co-PIs. Most of the work was really done by Jaime Barnes for her PhD.
Interactions between deformation and metamorphism: Controls on shear zone rheology and metamorphic memory. Joint with Adrian Brearley, along with former grad students Kurt Steffen and Jaime Barnes.
Proterozoic assembly of the northern Colorado Front Range. With collaborators Lang Farmer and John Aleinikoff, and former grad students Aaron Cavosie and Meghan Hodgins.
