Gas sampling for helium isotopes, Aguas Termales Santo Tomas, Peru.

My research group specializes in field-oriented, aqueous and stable isotope geochemistry to interrogate the origins and history of geofluids in continents, fluid-flow in faults, and fluid-rock-biosphere interactions. We address basic and applied problems in continental tectonics, low-temperature geochemistry, and energy and environmental geosciences (e.g., CO2 sequestration, geothermal energy exploration). A common theme in our work is the integration of multiple geochemical and isotopic tools along with an interdisciplinary approach to interpret the composition and temperature of modern and ancient fluids in the crust.

Recent News
August 2023: We are pleased to present the newly minted Dr. Coleman Hiett! Coleman masterfully defended his PhD dissertation "Volatile cycling and metasomatism in flat-slab subduction zones of the central Andes" and has now moved on to a post doc at the University of Arizona.
April 2023: Helium isotopes from the Denali fault! Check out our new work published in Geology that documents patterns mantle-derived helium in warm springs along the Denali fault, AK, with implications for mantel connections, deep fluid flux along faults, and how earthquakes may change fault hydrology. pubs.geoscienceworld.org/gsa/geology/article/51/6/576/622204/Roadblocks-and-speed-limits-Mantle-to-surface
April 2023: Our latest research from Peru has just been published in Communications Earth & Environment! In this paper we show that the microbial ecology and geochemistry of hot springs in the Peruvian Andes are directly linked to differences in tectonic setting between the flat-slab and back-arc subduction settings. Check it out here: https://rdcu.be/c9Dkg
March 2022: Check out PhD candidate Coleman Hiett's latest paper just published in Chemical Geology! Congratulations Coleman! Here we report new N2 and CO2 isotopic results from hot springs in Peru with implications for the transport of fluids from the mantle to surface about the Peruvian flat slab. We are honored to include this contribution in the special Chemical Geology issue in memory of Dave Hilton.
January 2022: Our Peru research group has a new paper out in Geology led by PhD candidate Tyler Grambling at UT Knoxville. Using the hydrogen stable isotope composition of synkinematic micas in mylonites, we document the infiltration of meteoric water deep into the Cordillera Blanca detachment with implications for the region's paleoelevation.
December 2021: Congratulations Ashley for publishing part of your MS research in Lithosphere! "Revised maximum depositional age for the Ediacaran Browns Hole Formation: Implications for Western Laurentia Neoproterozoic Stratigraphy"
April 2021: We are excited to welcome Shelby Litton (BS CU Boulder) and Kayla Chaudoir (BS Univ. of AZ) to our research team! They will be starting their MS programs at USU this fall.
February 2021: Coleman Hiett has published the first paper out of his Phd in EPSL: "3He evidence for fluid transfer and continental hydration above a flat slab". Congratulations Coleman!
November 2020: Check out Jace Koger's MS thesis work on the Hurricane Fault now published in Solid Earth! "Spatiotemporal history of fault-fluid interaction in the Hurricane fault, western USA"
June 2020: Congratulations Brandt Scott for publishing your MS research "Structural controls on crustal fluid circulation and hot spring geochemistry above a flat-slab subduction zone, Peru " in G-cubed!
