Biography

Mark James Hopwood, Associate Professor in the Department of Ocean Science and Engineering at Southern University of Science and Technology. He received his PhD in Ocean and Earth Science in 2015 at the University of Southampton (UK), where he worked with Peter Statham, one of pioneers of trace metal clean techniques that are required to study ultra-low levels of metals in the ocean. In 2015, Dr Hopwood joined GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany), working as a postdoc for one of the largest Marine Chemistry groups in the world under Eric Achterberg. He was also trained at the University of North Carolina Wilmington (USA). In 2019 he received his own funding from the DFG to investigate ice-ocean interactions around Greenland and Antarctica, and was appointed an Investigadore Adjunto for the Centro de Investigación Dinámica de Ecosistemas Marinos de Altas Latitudes (Valdivia, Chile) since 2017. Prof. Hopwood joined SUSTech in April 2021 and was appointed an Associate Professor in December 2021.

He has participated in over 9 research cruises and spent over 10 months on polar campaigns in Svalbard, Greenland and Antarctica. He has published more than 50 papers in leading oceanography journals, including Nature Communications, Nature Geoscience and Geophysical Research Letters. He is an associate editor for Journal Geophysical Research:Oceans.

During his spare time, Prof. Hopwood acts as a teaching assistant to introduce kids to marine science and paddleboard skills at a sports camp, letting the kids feel the charm of marine science. He is also a keen supporter of archery on campus.

He teaches undergraduate (OCE108 - Introduction to Carbon Neutrality, normally in the Spring semester) and postgraduate (OCE5030 – Marine Biogeochemical Cycles, normally in the fall semester). His research group is presently conducting large-scale (100,000 Litre) experiments in Dapeng, investigating the potential of negative emission techniques such as ocean alkalinity enhancement to store more CO2 safely in the ocean.
