Dr Casimir Y. Da-Allada is working at the National University of Sciences, Technology, Engineering and Mathematics of Abomey (UNSTIM) in Benin. He obtained a PhD in Physical Oceanography in 2013 on the Sea Surface Salinity variability of the Tropical Atlantic Ocean from the International Chair in Mathematical Physics and Applications (ICMPA-UNESCO Chair) of the Abomey-Calavi University (Benin) and Paul Sabatier University of Toulouse (France). He completed 3 years of post-doctorate in France working on the tropical oceans (Atlantic and Indian) and Atlantic Cold Tongue dynamics. He is currently working on a better understanding of the marine hydrological cycle variability in the tropical Atlantic. He uses observations data, analysis products and numerical simulations for his research work. Dr Da-Allada is also a member of the teaching team of the Master in Physical Oceanography and Applications at ICMPA-UNESCO Chair. He is in charge of the Introduction to Physical Oceanography course in this Master, and co-supervises the students’ internships. Finally, he is also Associated Researcher at the Fisheries and Oceans Research Institute of Benin (IRHOB).
