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, 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.
November 2021: Congratulations to Shane!! He has a new paper out in the Journal of Petrology, "Early-Paleogene magmatism in the Pinaleño Mountains, Arizona: evidence for crustal melting of diverse basement assemblages during the Laramide Orogeny."
October 2021: Portland Bound! Check out the groups' talks and posters next week at GSA.
October 2021: The Sed-Tectonics class had a great field trip to the Granite Mountains look at the Eocene-age Crooks Gap Conglomerate and Battle Springs Fm. Check out this drone footage of folks investigating a low-grade lignite interbed.
September 2021: Thanks to everyone who made this year's Rocky Mountain Field Trip such a great success! It was wonderful seeing everyone in person.
August 2021: There are two new additions to the group! Welcome to Dr. Lily Jackson, a post-doctoral researcher and Mollie Pope, a new M.S. student.
August 2021: Lots of last minute field work going on before the semester starts. Jessie and Shane met up with Dr. Allen McGrew in the Ruby Mtns., NV to look at anatectic rocks and Adam and I spent some time in the Black Hills, WY-SD looking at calcite veins.
August 2021: Special thanks to the Geologists of Jackson Hole for inviting me out for a talk and John Hebberger for hosting me. It was my first "in-person" talk in over a year!
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]
