Biography
Stephen Roberts has worked at the School of Ocean and Earth Science, University of Southampton, UK, for the past 40 years, serving as chair of the department between 2016 and 2020. Stephen has published more than 100 research articles investigating a wide range of mineral-forming systems. He has taken a particular interest in the formation of sea-floor massive sulfides, exploring the natural laboratories offered by sea-floor hydrothermal vent sites. Research highlights include sailing on the International Ocean Drilling Expedition (IODP) Leg 193 to the PACMANUS hydrothermal vent field in the Manus basin and IODP Leg 376 to the Brothers volcano, located on the Kermadec arc. He also participated in a remotely operated vehicle (ROV) campaign to the deepest known hydrothermal vent sites in the Cayman trough. On-land research has focused on the application of an integrated geologic, mineralogical, and geochemical approach to better understand the processes responsible for the Cu and Co ore deposits of the Zambian Copperbelt.
