Courses Taught:

GEOS 101/2 Dynamic Earth Lecture and Lab
GEOS 156 Geology of Natural Disasters
GEOS 201 Foundations of Geology Lecture and Lab
GEOS 301 Mineralogy
GEOS 311 Geochemistry
GEOS 345 Igneous and Metamorphic Petrology

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.
