The Basin Analysis & Helium Thermochronology Lab 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. Julie Fosdick and her research group draw upon numerous methods – including field mapping and stratigraphy, low-temperature thermochronology, geochronology, sediment provenance analysis, thermal history modeling, and structural reconstructions – to study tectonics and sedimentation.

Ongoing projects include work in the southern Central Andes (Argentine Precordillera, Sierras Pampeanas, Paganzo Basin), the Patagonian and Fuegian Andes, the San Andreas Fault System and Basin and Range Province of the Western U.S., and the Acadian Basin of the northeast U.S.


  • OK… we did it! Follow our research updates on Twitter @UConnBAHTL
  • We are excited to welcome new Research Faculty and Laboratory Technician, Dr. Megan Mueller, to the (U-Th)/He Thermochronology Lab!
  • Welcome new graduate students, Julian Biddle and Tony Edgington!
  • Dr. Fosdick was awarded a National Science Foundation CAREER grant to launch a new research and education program on CAREER: Resolving the detrital thermal signatures of sediment recycling in the Sierras Pampeanas, Argentina. Stay tuned for project updates…
