Elias Fakiris is a marine geologist with multidisciplinary scientific experience in remote sensing, passive and active acoustics, habitat mapping, marine geophysics, expert data assimilation, machine learning, and hydrodynamical modeling. Totaling more than 1,000 days of sea time around the Mediterranean, he has participated in more than 43 marine surveys, spanning topics from marine geology, geotechnical mapping, physical oceanography and geoarchaeology to habitat mapping, environmental studies, and passive acoustics. This has led to several multi-instrument (e.g., SBES, SSS, MBES, AGDS, ADCP, current meters, magnetometers, CTDs) and, more generally, ground-truthing (e.g., sediment sampling, water sampling, tow camera, and ROV operations) datasets being made available for industrial clients, European projects and research activities. His working experience has included multinational environments, such as the Center for Maritime Research and Experimentation (CMRE), La Spezia, Italy, where he was involved in 15EU research programs.
