Nick DeardorffAssistant Professor


  • B.S., University of Miami, FL — Marine Science and Geology
  • Ph.D., University of Oregon - Geology / Physical Volcanology

Courses Taught:

GEOS 102 Dynamic Earth Lab
GEOS 301 Mineralogy and Petrology
GEOS 303 Field Geology
GEOS 311 Geochemistry
GEOS 470 Research Methods in the Geosciences

Professional Interests:

Physical Volcanology, Petrology, Geochemistry, GIS. My research involves examining eruptive processes of volcanoes in both subaerial and submarine environments. I am interested in explosive eruption dynamics of submarine arc volcanoes, the resulting deposits, and geochemical exchange between magma and seawater and magma and hydrothermal fluids. I am also interested in lava flow morphologies and using remote sensing techniques, such as LiDAR, to quantitatively analyze volcanic terrains.
