I study volcanic rocks and minerals to investigate what controls the eruptive style of volcanoes

My previous research projects have included:

  • Trace element characteristics of zircon: assessing mineralization potential of granitoid intrusions and porphyries - postdoctoral project at Oregon State University
  • Controls on eruptive style and magma compositions at Mount Hood, Oregon - PhD dissertation
  • Magma sources and volatiles (water, carbon dioxide, sulfur, chlorine, fluorine) in melt inclusions from the Galápagos Archipelago - ScM thesis


Classes I have taught at Colgate include: 

  • Earth Resources (CORE Scientific Perspectives)
  • Environmental Geology (GEOL 101)
  • Sustainable Earth (GEOL 102)
  • Geochemistry (GEOL 403)


I'm always looking for new ways to make the classroom more engaging, inviting, and interactive!
