Bob Duncan is Associate dean for Student Programs and Professor of Oceanography at the . He studies the time scales and rates of volcanic processes in various plate tectonic environments, such as sea floor spreading ridges, volcanic arcs and hotspot chains, through radiometric age determinations of rocks and minerals by the 40Ar-39Ar incremental heating method. His recent work has focused on the geodynamic relationship between hotspots and large igneous provinces, and environmental consequences of catastrophic submarine volcanism.
