I joined the New Mexico Geochronology Research Laboratory in April 2024. I am interested in using geochronology and thermochronology to solve geologic problems ranging from the long term evolution of mountain ranges to impact dating. I am also interested in technique development for 40Ar/39Ar geo- and thermochronology. Depending on the focus, my research uses a combination of field work, geochronology, thermochronolgy and thermal-kinematic modelling.
