Stamatina Alexandri graduated in Geology from the University of Patras in Greece in 1983, and received a Master of Science in Oceanography from the University of Athens in 1988. She has worked at the Department of Geology & Marine Geophysics, of the Hellenic Centre for Marine Research in Greece since 1987. She has participated in more than 30 research cruises and several research projects involving, marine seismic reflection studies, marine gravity and magnetic surveys in Aegean Sea, multibeam bathymetry and deep-tow side-scan sonar studies. Her main field of interest includes the detailed mapping of the sea-bottom and sea-floor type identification via acoustic backscattering. Moreover, she enjoys the development of algorithms and mathematical techniques for enhancing features - structures, and extracting information from geophysical and remote sensing data. She has specialized in the synergy of multi-frequency deep-tow sidescan sonar data, multibeam swath data and coincident acoustic imagery for sea floor type identification, in regions of the Mediterranean ridge that have been affected by tectonic activity, mud diapirism and dissolution of evaporites which locally produces brine lakes. She has the main responsibility for the operation of the multibeam system on the R/V AEGAEO, and has successfully organized several research cruises for the detailed mapping of the sea bottom in selected areas in the Aegean sea and Eastern Mediterranean.
