Jim in the PyreneesI am a research associate and lab manager at the University of Colorado – Boulder specializing in thermochronology and tectonics and in charge of managing the day-to-day operations of the CU TRaIL (Thermochronology Research and Instrumentation Laboratory), under the direction of Professor Becky Flowers. My research uses (U-Th)/He, fission-track, and 40Ar/39Ar thermochronology to understand the thermal evolution of the lithosphere and decipher long-term patterns of exhumation, deformation, and erosion. My current research projects include ongoing work in the Basin-and-Range Province, the Pyrenees, the Colorado Rockies, and the moon. I am also involved with noble gas laboratory development and automation, (U-Th)/He technique development, and inter-laboratory calibration efforts. As an instructor I have taught a wide range of earth science classes including introductory geology, structural geology, geologic hazards, climate change, and field geology.
