William E. Seyfried Jr., George R. Gibson Professor of Geoscience in the Department of Earth Sciences at the University of Minnesota. From 1993 to 2006 he served as Head of the N. H. Winchell School of Earth Sciences at the University of Minnesota. Throughout his career he has been involved in experimental studies to constrain heat and mass transport processes in seafloor hydrothermal systems. These studies have benefitted greatly from the more recent development and application of in-situ chemical sensor technologies at deep sea vents, which has been accomplished in collaboration of Dr. Kang Ding. In the following image, Seyfried is congratulating former doctoral student, Dionysis Foustoukos, on a successful ALVIN dive.






Kang Ding, Senior Research Associate received his Ph.D. degree in geochemistry in 1987 at Institute of Geochemistry, Chinese Academy of Science, under the supervision of Dr. Guangzhi Tu. He is currently a senior research associate in University of Minnesota. His field of research involves hydrothermal chemistry with an emphasis on subseafloor systems. These studies are mainly carried out through experimental effort at elevated temperatures and pressures, especially in the supercritical region of water. In past 15 years, he has been involved extensively with deep submergence science for developing and applying in situ chemical sensors to study hydrothermal fluids venting at mid-ocean ridges










Chunyang Tan, Research Associate received his Ph.D. degree in Engineering in Zhejiang University, China in December 2011. He is currently a research associate in the Department of earth Sciences at the University of Minnesota. His research interest focuses on in-situ chemical sensor technology for applications in hydrothermal vent fluid at elevated P-T conditions. His efforts also involve high P-T reaction systems and the development of new experimental and theoretical modeling approaches that can be used to supplement field data.










Andrew Fowler, Postdoctoral Research Associate Andrew completed his Ph.D. in geology at the University of California Davis in 2016. He studies water-rock reactions in seafloor hydrothermal and terrestrial geothermal systems using experimental investigations, theoretical modeling techniques, and chemical and isotopic analyses of natural samples. Knowledge of deep water-rock reactions in terrestrial geothermal systems support the sustainable use and development of geothermal energy, by helping constrain subsurface fluid chemistry, temperature regimes, and the distribution of renewable energy resources. Study of sub-seafloor seawater-rock reactions are important for understanding hydrothermal influences on ocean chemistry and the composition of oceanic crust on Earth and elsewhere in the solar system. Andrew currently studies water-rock reactions under extreme conditions approaching the magma-hydrothermal interface. Follow Andrew on Twitter @ThingsHotSpring











Peter Scheuermann, Ph.D. Candidate Originally from Pittsburgh, PA, Peter graduated from Carleton College in 2012 with a degree in geology.  His current research involves experiments at temperatures and pressures relevant to seafloor hydrothermal vents to investigate elemental partitioning and mineral solubility in vapor-liquid-mineral systems.
