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

Current research with students at Colgate:

• Testing the controls on eruption size and style at intermediate arc volcanoes: Evidence from the Holocene record at Augustine Volcano, USA

Some previous projects:

• Trace element characteristics of zircons from granitoid intrusions and porphyries in Peru
• Controls on eruptive style and magma compositions at Mount Hood, Oregon
• Magma sources and volatile elements (water, carbon dioxide, sulfur, chlorine, fluorine) in lavas of the Galápagos Archipelago

Classes I currently teach include: 

• Dangerous Earth (Core Science)
• Earth Resources (Core Science)
• Environmental Geology (GEOL 101)
• Sustainable Earth (GEOL 102)
• Volcanology (GEOL 260)
• Geochemistry (GEOL 403)

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