Project chief for USGS, Water Resources Division program on "Hydrologic Hazards and Processes at Alaska Volcanoes". Areas of expertise are geomorphology, hydrology, and Quaternary geology. Current investigations and research activities include hydrologic hazard assessments at Alaska Volcanoes, volcano-glacier interactions and the generation of floods and lahars, and Holocene geomorphic history of Alaska volcanoes. Presently working at Aniakchak Caldera, Adak Island, Mt. Spurr, and Mt. Redoubt.
