My research focuses on applying geochronology, thermochronology, radiogenic isotope tracing, field geology, structural analysis, and geochemistry to processes of lithospheric evolution and Earth history.  I oversee a radiogenic isotope geology lab in Geosciences at Princeton, which hosts low-blank clean room facilities and two thermal ionization mass spectrometers (TIMS), in addition to rock and mineral separation and characterization facilities. Much of the lab's focus is on improving high-precision U-Pb geochronology and expanding its range of applications.  We also measure high-precision Sr isotopes and integrate our work with the ICPMS lab, run by professor Higgins. Click on tabs to the left for details about particular research focuses and ongoing collaborations with other people at Princeton and around the World.

Interested in doing a Ph.D or post-doc? Have interesting research that would benefit from high-precision U-Pb geochronology? Send me an email: [email protected]
