Dr. Jacqueline Uku
Dr. Jacqueline Uku is a Chief Research Scientist at KMFRI and conservation leader who works on the ecology and physiology of marine flora with a special focus on seagrasses. She has a special interest on community development having worked extensively with coastal communities during the Kenya Coastal Development Project as the Project Leader. She serves as the Coordinator of Research at KMFRI. Jacqueline is the recent past President of the Board of the Western Indian Ocean Marine Science Association (WIOMSA) and also serves on the Executive Committee of the Scientific Committee for Oceanic Research (SCOR). She is currently serving as the Chair of the Africa Ocean Decade Taskforce, whose main mandate is to support the implementation of the Africa Ocean Decade Roadmap (https://unesdoc.unesco.org/ark:/48223/pf0000381488). Jacqueline is also a member of the expert group for Ocean Literacy.
