Research Overview

My research involves understanding Earth surface change processes, with emphasis on volcanic flows such as lavas and domes. I use field measurements of active processes using laser scanning, close-range photogrammetry, mm-wave radar, infrared and remote time-lapse imaging, and UAVs and am currently exploring the use of structure-from-motion algorithms for facilitating 3D surface generation from photographs. Other areas of interest include volcanic fluid dynamics and plume processes.
