Dr. Dionysios Raitsos is a Senior Research Scientist at PML. He received his BSc in Marine Biology, MSc in Fisheries Science, and PhD in Satellite Oceanography (from Newcastle, Aberdeen, & Plymouth respectively). He worked for 6 yrs as a post-doctoral researcher in Greece (HCMR) and Saudi Arabia (KAUST). He joined the Remote Sensing Group (RSG) at PML in 2013.

Dionysis is interested in satellite remote sensing applications in ocean colour, plankton, and fisheries in relation to the regional environmental variability and broader climate oscillations (Atlantic, Pacific and Mediterranean Sea). Also, following an inter-disciplinary approach, synergistically analysing available datasets, we are studying the function of the Red Sea ecosystem, and investigating the large–scale variability of this pristine tropical ecosystem. On these subjects, he has published 44 papers in peer-reviewed journals, and contributed in 3 books.

He has worked in several EU FP-6 and FP-7 projects, and is a reviewer in 22 international Journals including: Limnology and Oceanography, Remote Sensing of Environment, Ecology Letters, Plos One, Nature Publishing Group etc. Dionysis is a Review Editor in Frontiers in Marine Science, and a Guest Editor for Remote Sensing.
