Research interests:
My research focuses on understanding the structural evolution of contractional and extensional mountain belts, including the Himalayas, the Andes, the North American Cordillera, and the Basin and Range Province. I integrate mapping-based field data with a diverse suite of quantitative datasets, including geochronology, thermochronometry, metamorphic temperatures and pressures, microstructural analyses, regional tectonic reconstructions, and balanced cross sections. Much of my recent research involves field-based evaluations of the predictions of models for the dynamics of mountain belts. Please see my research page for more details.

Picture from Summer, 2023 field work in Ladakh, India:
In July-August, 2023, I went with WSU PhD student Adelie Ionescu and professor Matt Kohn from Boise State University to perform field work in the Northwestern Indian Himalaya, in the Tso Morari region of Ladakh and further to the southwest in Himachal Pradesh. Here's a picture of Adelie and I, with Cambrian sedimentary rocks of the Tethyan Himalayan sequence behind us.

Picture from 2019 GSA annual meeting in Phoenix
In September, 2019, five students from my research group (from left to right: Russell DiFiori, Ryan Anderson, Nolan Blackford, Jesslyn Starnes, and Kimberly Kramer) traveled to the GSA annual meeting in Phoenix to present their research.

Picture from Fall, 2016 Bhutan field work:
In Fall, 2016, two of my graduate students, Laura Pianowski and Jesslyn Starnes accompanied me, collaborator Stacia Gordon, and collaborator Robert Miller, on a field expedition to Bhutan. This picture shows Laura (left) and Jesslyn (right) in their kiras, the traditional Bhutanese female clothing. Behind them is Bhutan's famous Takstang monastery.

In March, 2012, while mapping in southeast Bhutan, by chance Nadine McQuarrie (center), Tobgay (right) and myself (left) happened to meet his majesty Jigme Khesar Namgyal Wangchuk, the 5th king of Bhutan, and queen Jetsun Pema. This picture was taken that evening at their camp.
