John L. Smellie is a professor in the Department of Geology at the University of Leicester. He is the leading expert on Antarctic glaciovolcanism and has extensive experience working on Iceland's glaciovolcanoes. He is a prolific author, having produced over 190 publications, including 10 edited volumes. Professor Smellie is the co-founder and first Chair of the IAVCEI/IACS Commission on Volcano-Ice Interactions, and, in 2000, was co-convener of the first International Conference on Volcano-Ice Interactions on Earth and Mars. He has been awarded the Polar Medal, conferred by Her Majesty The Queen, is co-Chair of the SCAR (Scientific Committee on Antarctic Research) Expert group on Antarctic Volcanism, and has three geographical features in Antarctica named after him. Benjamin R. Edwards is an associate professor in the Department of Earth Sciences at Dickinson College, USA. He has over 24 years of field experience working in remote regions of British Columbia, Iceland, Alaska, Russia and South America on modern and ancient glaciovolcanoes, and is one of the leading researchers in the rapidly expanding field of large-scale experimental volcanology, specifically focused on lava-ice and lava-water interactions. Dr Edwards is also a co-founder of the IAVCEI/IACS Commission on Volcano-Ice Interactions, and has convened various special sessions on volcano-ice interactions at AGU, GSA, EGU, and IUGG international conferences.
