Jason Hall-SpencerView profile
Professor
Professor Jason Hall-Spencer is a globally recognized marine biologist at the University of Plymouth and a full professor at the University of Tsukuba (Japan), with an adjunct role at Xiamen University. His research focuses on ocean acidification, invasive species (e.g., lionfish), and climate change impacts on marine ecosystems. He pioneered the use of underwater CO2 seeps as natural analogues for climate change studies, a methodology now adopted globally. His work has influenced policies to protect deep-water corals and Arctic reefs, and he leads projects like RELIONMED to combat lionfish invasions in the Mediterranean. Education: Studied Applied Marine Biology at Heriot-Watt University, completed a PhD on coralline algae at Millport Marine Station, and conducted fieldwork across Europe, Asia, and the Pacific. His career includes discovering UK deep-water coral reefs and Arctic reefs, leading to their legal protection. Research Interests: Ocean acidification effects on marine organisms, invasive species management, CO2 seep dynamics, coral reef ecology, and marine conservation. His work combines field experiments, policy advocacy, and community engagement to address global marine challenges. Grants and Collaborations: Secured €1.7M from the EU Life Programme for lionfish control and a $400K grant on plankton dynamics. Collaborates with organizations like the Marine Biological Association and international researchers on projects such as the Ocean Organ to visualize CO2 impacts. Labs/Teams: Leads the Marine Conservation Research Group at Plymouth, coordinating initiatives like RELIONMED and influencing global marine policies through partnerships with governments and NGOs.
