My interests include metamorphic petrology, inorganic geochemistry, and Precambrian geology.  Two research initiatives are currently funded by the National Science Foundation.  One project is aimed at deciphering the geochronologic record of Precambrian thermotectonism in the Wyoming Province and the Adirondack Mountains.  The other is focused upon elucidating the crystal-chemical basis for argon retention and closure temperatures in amphiboles and micas.
