Dr. Samuel Ukpong Okon is a British-trained Ocean Scientist and a Chinese-trained Coastal/Ocean Engineer. He is currently a Lecturer and Oceanographer at Akwa Ibom State University in Nigeria and a Postdoctoral Research Associate at Zhejiang University in China. 
Dr. Sam Okon graduated with a B.Sc in Marine Biology from the University of Calabar and was employed in 2013 as a Graduate Assistant in the Department of Marine Sciences, Akwa Ibom State University. In 2014, he got admission into the School of Ocean Sciences, Bangor University in the United Kingdom, where he completed his M.Sc program in Physical Oceanography. In 2017, the Chinese Government awarded him the prestigious Marine Scholarship of China to study ‘Colliding Gravity Currents’ at the Sediment and Environmental Fluid Mechanics Laboratory in the Ocean College of Zhejiang University, China. This research led to his Doctoral dissertation on the hydrodynamic characteristics of symmetric and asymmetric colliding gravity currents. He graduated with a Ph.D. in Ocean Engineering and was offered a postdoctoral research position in 2022. With his Chinese research teammates, Sam has been involved in research projects funded by the National Natural Science Foundation of China, the National Key Research & Development Program of China, and the Fundamental Research Funds for the Central Universities in China. 
As a broad-based oceanographer, Dr. Sam has also studied several oceanography-related short professional courses and obtained certificates in Blue Economy from James Michel Blue Economy Research Institute and the University of Seychelles, Seychelles; Fishery Oceanography for Future Professional from International Training Center for Operational Oceanography (ITCOocean), India; Marine Spatial Planning (MSP) from IMBeR Interdisciplinary Marine Early Career Network, Nova Scotia, Canada; Climate Dynamics and Air-Sea Interactions from First Institute of Oceanography, Qingdao, China; Transdisciplinarity in Fisheries & Ocean Sustainability from Global Partnership for Small-Scale Fisheries, Newfoundland, Canada; and Remote Sensing of Coastal Ecosystems from National Aeronautics and Space Administration (NASA). As a Postdoc in China, Dr. Sam is currently researching the interaction between Density Current and the Foundation Structure of Offshore Wind Turbine Using an Artificial Intelligent (IA) Algorithm. He is a member of several professional organizations, including the International Association for Hydro-Environment Engineering and Research (IAHR), the American Society of Civil Engineers (ASCE), the Organization of African Academic Doctors (OAAD), etc. 
Dr. Sam also completed a Ph.D. enrichment course on ‘Sustainable Development of Life Below Water’ at the Bergen Summer Research School of the University of Bergen in Norway, with European Transferable Credits. He is a multiskilled oceanographer with research experience across different disciplines of ocean sciences. His multidisciplinary oceanography background grants him a wealth of research experience in Geological, Physical, Biological, and Fisheries Oceanography. He is interested in estuarine and marine pollution, fluid dynamics, sediment transport, contaminant transport, experimental and numerical modeling of buoyant plumes, etc. Besides his sea survey experience on the Prince Madog research vessel along the Menai Strait and the English Channel in Europe, Dr. Sam currently uses laboratory experiments and numerical simulations to explore how large-scale geophysical flows collide in the atmosphere, estuaries, and oceans. He has attended and presented papers at several international conferences. He has published in several reputable SCI journals, including Physics of Fluids, Journal of Marine Science and Engineering, Environmental Engineering Research, Environmental Toxicology, and Pharmacology, etc.
