I am working with Drew Coleman on the emplacement history of the Questa porphyry molybdenum deposit in New Mexico. We are using zircon and titanite U-Pb geochronology in conjunction with Re-Os geochronology in molybdenite to construct thermal histories of plutons associated with mineralization. Ultimately, we are investigating if plutons related to porphyry ore deposits are assembled incrementally, or as large bodies of mostly liquid magma.

Currently, I am working with Allen Glazner on refining and updating the NAVDAT geochemical database.
