Mark James Hopwood

Associate Professor Department of Ocean Science and Engineering

Mark Hopwood studied Chemistry at undergraduate and masters level at The University of Manchester (UK) before moving to The School of Ocean and Earth Science at The University of Southampton (UK) to complete a PhD in iron biogeochemistry in freshwater and coastal environments. Following completion of his PhD he moved to GEOMAR in Kiel (Germany) where he completed postdocs working the projects Ocean Certain (EU) and Climate-Biogeochemistry Interactions in the Tropical Ocean (SFB754).

He was then awarded DFG funding to pursue his own research investigating how climate change is affecting marine biogeochemistry around Greenland and the Antarctic Peninsula. He has participated in over 8 oceanographic research cruises and spent over 8 months on polar field campaigns in Svalbard, Greenland and Antarctica.

In 2021 he moved to SUSTech. His research interests are how biogeochemistry in the coastal ocean will respond to climate change on decadal timescales. Ongoing research projects include cruise work across the Pacific, Arctic and Antarctic Peninsula. Candidates interested in PhD or postdoc positions are welcome to get in touch.
