My interests involve the study of volcanic phenomena such as pyroclastic and debris flows, and their associated hazards. I am interested in the geomorphic implications of explosive volcanism, studying the topographic changes around active volcanoes that result from the emplacement of new material by pyroclastic and debris flows. Currently, I use differential GPS, GIS and computational flow modeling techniques in addition to traditional fieldwork methods. I am interested in expanding these methods to include remotely sensed data such as optical, RADAR and LIDAR, to further enhance our understanding of active geomorphic processes on volcanoes. The other focus of my research is geared towards understanding how geomorphic processes relate to volcanic hazards and the risks faced by people living near active volcanoes. Other interests include large debris avalanches and related volcanic sector collapse mechanisms, and geomorphology and hazards of non-volcanic debris avalanches and debris flows.
