research overview

  • I use thermochronology, geochronology, and geologic observations to address problems in continental tectonics and mantle dynamics, with particular focus on understanding the coupling of deeper Earth and surface processes over extended (10s-100s Ma) timescales. I also direct a (U-Th)/He geochronology lab, containing an Alphachron He extraction line and Agilent 7900 quadrupole ICPMS, in which we emphasize the development and refinement of both conventional (e.g., apatite, zircon) and novel (e.g., conodonts, perovskite, garnet) He thermochronometers. My group especially seeks creative, collaborative applications of (U-Th)/He data to problems in fields in which the technique has not typically been utilized (e.g., to constrain lunar impact histories, calibrate mantle dynamic models, date kimberlite emplacement). Our goal is to consistently remain open-minded to new ways of thinking about the significance of our results.
