- Our paper on Miocene surface uplift and moisture-source change in the southern Central Andes (~32°S), resolved with paired volcanic glass and pedogenic carbonate isotopes, has been accepted in Earth and Planetary Science Letters.
Paleoelevation estimates for the Manantiales basin from pedogenic carbonate (circles) and volcanic glass (triangles); carbonate data record ~1.9 km of surface uplift, mostly between ~18.6 and 16.5 Ma. MCO, Miocene Climatic Optimum. - A great GSA Connects in Denver: Amarissa Cramer and Tiana Hursh presented posters on the detrital zircon and basin record of coastal Chile, and I convened the Pardee Keynote Symposium Bottoms Up and a session on the pre-Neogene tectonic evolution of South America, co-taught a short course on detrital geochronology data, and gave an invited talk, Whence the lustrous stones?, on the provenance of Paleogene gravels in the Andean foreland.

- I started as an Assistant Professor in the Department of Earth, Energy & Environment at the University of Calgary, and I am recruiting M.Sc. and Ph.D. students for funded positions.
- I spent the summer as a Visiting Postdoctoral Scholar at Stanford University, working with Stephan Graham on the Mesozoic forearc record of coastal Chile.
- Congratulations to Parker Hazelbush on finishing his B.S. at Idaho State, and to Tiana Hursh on presenting our coastal Chile basin work at the ISU Research and Creative Works Symposium.
- Six weeks of fieldwork in the Coastal Cordillera of Chile with ISU undergraduates, targeting the Triassic–Jurassic forearc basin record of terrane accretion; see the research group page for photos.
- Presented new crustal-thickness results from the southern Central Andes at GSA Connects, and gave invited talks at Idaho State, the University of Alaska Fairbanks, and the Montana Bureau of Mines and Geology.
- Awarded an NSF Earth Sciences Postdoctoral Fellowship (EAR-PF) and joined Kurt Sundell’s group at Idaho State University to study terrane accretion in the Chilean forearc.
- Defended my Ph.D. at the University of Arizona: Cretaceous to Cenozoic Evolution of the Southern Central Andes and Basins Therein (advisor Peter DeCelles).
