Brian Jicha in the field.

Current Research Interests
• Using U-Th mineral isochrons to determine pre-eruptive crystal residence times in the magma
• Quantifying the long-term eruptive histories and evolution of active arc volcanoes
• Investigating island arc growth and development over the last 50 Ma
