My research group focuses on the tectonics of convergent margins and the evolution of the continental lithosphere. Research goals are generally centered around identifying and resolving interactions between orogenic magmatism, crustal deformation, sedimentation, and lithospheric dynamics in Cordilleran and collisional orogenic systems. Most research projects are field-based, but we also employ lab-based analytical, experimental, and numerical methods. Please visit the research page to learn more about ongoing research.
July 2021: PhD student Jessie Shields and I just returned from some field work in central CA looking at Franciscan melange. Special thanks to John Wakabayashi and the Fresno State crew for showing us around.
June 2021: My co-authors and I have a new invited review paper out in Lithos, "The causes of continental arc flare ups and drivers of episodic magmatic activity in Cordilleran orogenic systems." [pdf]
June 2021: Thanks to all the students who made this year's in-person field camp at Seminoe State Park a wonderful success!
June 2021: Pete DeCelles and I have new paper out in Tectonics, "Beveling the Colorado Plateau: Early Mesozoic Rift-Related Flexure Explains Erosion and Anomalous Deposition in the Southern Cordilleran Foreland Basin." [pdf]
June 2021: Kurt Sundell has a new paper out in GSA Today, "Jurassic to Neogene Quantitative Crustal Thickness Estimates in Southern Tibet" that I am co-author on. [pdf]
May 2021: Congratulations to Cody Pridmore, who defended this MS thesis! Also, Jessie and I were recently on Wyoming Public Radio to talk about the Cordilleran Anatectic Belt (link)
May 2021: I have a new paper out in Geology, "Diapiric relamination of the Orocopia Schist (southwestern U.S.) during low-angle subduction," which is my first single-author paper [pdf]
April 2021: Congratulations to Amanda Rossi, who will intern with the USGS in Golden, CO this summer!
March 2021: My co-authors and I have a new article out in Earth-Science Reviews, "The North American Cordilleran Anatectic Belt," which is the culmination of a graduate seminar in Spring 2020 [pdf]
August 2020: Two new graduate students have joined the group! Welcome to Jessie Shields and Amanda Rossi! Bios.
July 2020: Fangyang Hu has a new paper out in GRL tracking elevation changes in Tibet that I am a co-author on [pdf].
June 2020: UWyo Field Camp this year was completely online/virtual. I put together several Google Earth Projects for the week focused on the Seminoe State Park. Check them out HERE.
April 2020: Wang Xin as a new paper out in Geology, "The role of the westerlies and orography in Asian hydroclimate since the late Oligocene" that I am a co-author on. Check it out. [pdf].
March 2020: Adam Trzinksi and I sneaked in some field work over Spring Break in the northern Chiricahua Mtns. It looks like the last field work for a while with COVID taking over.
February 2020: The new FTIR spectrometer was finally installed and is up and running
February 2020: My co-authors and I have a new article out in Geology, "Geochemical evidence for an orogenic plateau in the southern US and northern Mexican Cordillera during the Laramide orogeny." [pdf]
