The Basin Analysis & Helium Thermochronology group at UConn focuses on reconstructing ancient phases of mountain building and erosion to understand how tectonics, erosion, and climate interact to influence Earth’s dynamic mountain belts. Dr. Fosdick and her students draw upon numerous methods in our research, including field mapping and stratigraphy, low-temperature thermochronology, provenance analysis, geochronology, and structural reconstructions.

Ongoing thermochronology and basin analysis projects include work in the Magallanes Basin in the Patagonian Andes, the Argentine Precordillera of the southern Central Andes, the San Andreas Fault System, Basin and Range Province, and Appalachian Mountains.


  • Welcome, Adam Goldsmith from UT Austin! Beginning late February 2018, Adam joins BAHTL as the new (U-Th)/He Laboratory Technician.
  • Exciting news!! BAHTL has received NSF Instrumentation & Facilities funding (Award 1735492) for full-time laboratory technician support. This award will enable the broader Earth science community to gain access to the (U-Th)/He facility and will support visitor training and applications and development in geothermochronology.
  • This Fall 2017, we welcome three new group members: Dr. Andrea Stevens Goddard (Postdoctoral Scholar), Isabelle Bristol (Graduate Student), and Jackie Giblin (Graduate Student) – Welcome to UConn!
