Welcome to the Fosdick Lab in the Department of Earth Sciences at UConn!

Our research investigates ancient and active mountain-building to understand how tectonics, magmatism, erosion, and climate interact to shape Earth’s lithosphere and dynamic landscapes.


Dr. Julie Fosdick and her research group – the Basin Analysis and Helium Thermochronology Laboratory (BAHTL) – draw upon numerous methods to study tectonics, erosion, and sedimentation. We use field mapping and stratigraphic analysis, low-temperature thermochronology, geochronology, sediment provenance analysis, thermal history modeling, and subsidence analysis.

Our lab group includes graduate students, postdocs, and undergraduate researchers – along with collaborating scientists at UConn and beyond. Learn more about us on group personnel, research, and the (U-Th)/He thermochronology facility.
