While my Ph.D. research focused on near-inertial waves in the ocean, my scientific interests gradually expanded through time to include the interannual variability of the Mediterranean Sea and the role of the exchanges with the Black Sea, small-scale processes and internal waves, air-sea exchanges and physical-biological interactions. Most emphasis has been given to the revelation of the insulating role of the Black Sea Waters in the North Aegean Sea, as well as the analysis of the turbulent diffusion acting in its deep sub-basins during stagnation periods. Current activities include the application of Lagrangian methodologies, the use of a coastal HF radar in the long-term assessment of the Aegean-Black Sea exchanges, investigation of environmental impacts of shipping, development of a coastal observatory in the North Aegean Sea.
