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.


  • Welcome to Dr. Cullen Kortyna, our newest Fosdick Lab member and Postdoctoral Scholar!
  • Wrapped up our Summer 2022 ConnCAP Rocks! activities with nine incredible high school students. Check out the project on making ‘mineral medallion maps’ to learn about rocks and minerals…
  • HUGE congratulations to Tony Edgington on his NSF Graduate Research Fellowship award! Woo hoo!
  • OK… we finally joined Science Twitter! Follow our research updates @UConnBAHTL
  • We are excited to welcome new Research Assistant 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…
