   abstract: I work with VDAP's foreign partners to better understand the eruption
     histories and hazards of their dangerous volcanoes. My work focusses on volcanic
     stratigraphy with an emphasis on field-based projects. I also develop regional
     and local tephrostratigraphies using ash layers in cores and am developing new
     applications for long-lived plant species to provide insight into past volcanic
     activity.
