   abstract: I am a Research Geologist at the U.S. Geological Survey in Denver, CO.
     My areas of expertise include igneous petrology, economic geology, experimental
     petrology, geochemistry, and volcanology. I spearhead the melt inclusion analysis
     capabilities in the Denver Inclusion Analysis Laboratory.

   abstract: "I'm interested in applying melt inclusion studies and experimental\
     \ petrology to learn more about how metals are concentrated and partition from\
     \ magmas into ore-forming fluids that generate economic ore deposits.I am currently\
     \ investigating: (1) magmatic contributions to iron oxide-rare earth element\
     \ (IOA-RE) and iron oxide-copper-gold (IOCG) deposit genesis in the Missouri\
     \ iron province, (2) concentrations and partitioning of Li in highly evolved\
     \ rhyolites in the western US as a source for economic Li brines and clays,\
     \ (3) quantifying critical elements (Li, W, REE) in rift related volcanic systems,\
     \ and (4) testing the magmatic model for Carlin-type Au deposit genesis in Nevada.\
     \ I recently completed a 5-year project entitled \"Magmas to Metals\" focused\
     \ on melt inclusion and high-spatial resolution mineral geochemical analyses\
     \ to explore igneous systems related to IOA-REE and IOCG mineralization in the\
     \ St. Francois Mountains of SE Missouri.During my Ph.D. I used petrologic and\
     \ geochemical methods to investigate the magmatic-hydrothermal transition at\
     \ the porphyry-Cu-Mo deposit in Butte, Montana, and the crustal \"plumbing system\"\
     \ of a stratovolcano in the Cascades.Recent StudentsNational Association of\
     \ Geoscience Teachers-USGS Interns, 2018, 2014St. Lawrence University Summer\
