Dr. Judith Okello

Dr. Okello has worked along the coast of Kenya in different organizations and in varying capacities for slightly over 10 years, a period during which she has gained a wide range of experience in ecological management of coastal resources.  At KMFRI, she has been serving as a Research Scientist mainly working in the mangrove ecosystem with special interests in stress-driven physico-chemical dynamics and the associated physiological response of mangrove trees.  Dr. Okello has also played a pivotal role in development of a number of key documents which are instrumental in the management of Coastal ecosystems including, The National Mangrove Ecosystem Management Plan- Launched in 2017; and The Second Edition of the State of Coast Report (2018) among others. In terms of collaboration with other institution, She is currently engaged as one of the key experts in the Kenya Climate Change Adaptation Program housed by the Coastal Development Authority (CDA).
