Dr. Erick Okuku
Dr Okuku has over 18 years in marine research ranging from marine ecology, pollution, plankton, biotoxins. He has lately been involved marine litter assessments, ocean acidification and use of radioisotopes to reconstruct pollution history and determine sediment accretion rates. He has coordinated more than 20 project in the last 18 years and has published a number of peer reviewed articles.
