I study the ground motion and low-frequency sound produced by volcanoes and rocket launches. I build tools that help observatory scientists follow changes during unrest, and recover older recordings so we can ask new questions about past eruptions.
My perspective comes from working on duty at volcano observatories. A catalog may show a rise in earthquake counts, but a duty scientist also needs to see which stations are recording tremor, when its character changed, and whether the source is moving. Those questions led me to build IceWeb in Alaska and to work on tracking pyroclastic flows on Montserrat.
At USF I work with students and collaborators on two very different kinds of field records: signals from present-day rocket launches at Kennedy Space Center and recovered recordings of earlier eruptions. In both cases, knowing the history of the instruments matters as much as knowing how to process a waveform.
