   intro_statements:
   - I am a Mendenhall fellow based in Reston, Virginia. My work with the Coastal
     Basement Geology of the Southeastern U.S. Project involves mineralogical, geochemical,
     and isotopic studies of rocks from deep wells and the production of geologic
     maps from these data. The list of Publications below is automatically generated
     and incomplete. Please contact me directly for a copy of my current CV.
