Biography
I am a seismologist for the USAID-USGS Volcano Disaster Assitance Program, based at the Cascade Volcano Observatory in Vancouver, WA. I write, maintain, and apply automatic processing tools to assist data interpretation and eruption forecasting efforts. I also co-teach the Seismology section at the Center for the Study of Active Volcanoes — an eight week summer program on volcano monitoring basics. In my free time, I enjoy running, biking, and skiing.
Pre-USGS Work Experience:
Nanyang Technological University, Singapore (2014–2015)
- Asian School of the Environment/Earth Observatory of Singapore
- Lab Instructor, Field Instructor, Lab Manager
Peace Corps / Raung Volcano Observatory, East Java, Indonesia (2011–2013)
Education:
Michigan Technological University MSc, Geology (May 2014)
DePauw Univeristy BSc, Geology (May 2010)

The 2017-19 activity at Mount Agung in Bali (Indonesia): Intense unrest, monitoring, crisis response, evacuation, and eruption
After 53 years of quiescence, Mount Agung awoke in August 2017, with intense seismicity, measurable ground deformation, and thermal anomalies in the summit crater. Although the seismic unrest peaked in late September and early October, the volcano did not start erupting until 21 November. The most intense explosive eruptions with accompanying...

Greg; Pallister, John S.; Lowenstern, Jacob B. Prevalence of seismic rate anomalies preceding volcanic eruptions in Alaska
Seismic rate increases often precede eruptions at volcanoes worldwide. However, many eruptions occur without such precursors. Additionally, identifying seismic rate increases near volcanoes with high levels of background seismicity is non-trivial and many periods of elevated seismicity occur without ensuing eruptions, limiting their usefulness for...
