John obtained his BSc Environmental Science degree from the University of Cape Coast (UCC), Ghana, where he served as a research and teaching assistant. Subsequently, he pursued his MSc Biology: Environment, Biodiversity and Ecosystems at the Vrije Universiteit Brussel (VUB), Belgium. John also holds a double master certificate in Spatial Ecotoxicology and Ecotoxicological Risk Assessment (open community approach) from the University of Koblenz-Landau, Germany.
John was appointed on January 2018 onto the Mapping, Monitoring and Modelling Key Processes and Controls on Cold-Water Coral Habitats in Submarine Canyons (MMMonKey_Pro) project under the supervision of Prof Andy Wheeler and Dr Ruth Ramsay. His project investigates the key control processes on the spatial distribution of benthic megafauna in cold-water coral (CWC) rich habitats in the Porcupine Bank Canyon (PBC), NE Atlantic. He utilizes data from hull-mounted multibeam echosounder (MBES), conductivity-temperature-depth (CTD) and remotely operated vessel (ROV) based benthic video surveys to map and monitor CWC habitats in the canyon. He also employs histology and molecular techniques to assess the health status of the main framework forming scleractinian corals Lophelia pertusa and Madrepora oculata as part of his research.
