    Research Assistant ProfessorManager, Electron Microprobe LaboratoryDepartment of Physical ScienceConcord University Athens, WV 24712

    = Teaching =

    GEOL 101 - Earth Processes and Environment GEOL 375 - Igneous, Sedimentary, and Metamorphic Petrology GEOL/CHEM/PHYS 420 - Electron Microscopy and X-ray Microanalysis

    = Research =

    Tephrochronology
    * especially the Cascades and Alaska
    * e.g. Summer Lake, OR; Glacier Peak, WA; Mt. St. Helens, WA; Newberry Volcano, OR

    Pyroclastic volcanology
    * especially field-based studies of both proximal and distal deposits
    * e.g. Newberry Volcano

    Electron Probe Microanalysis (EPMA)
    * manage and operate one of the very few fully-operational, research-grade electron microprobes located at an undergraduate university - four WDS spectrometers and a recently installed (2012) 30mm2 SDD EDS spectrometer with extensive software (including automated particle analysis)
