Dr. Grigoris P. Rousakis is a marine geologist, holding since February 2006 an Associate Researcher position in the Institute of Oceanography, Hellenic Centre of Marine Research (HCMR), in Anavyssos, Greece.

During 1983-1984, he has worked at the Engineering Geology Laboratory, Institute of Geology and Mining Exploration (IGME) focused on the estimation of soil geotechnical characteristics.

In 1986 he started to work at NCMR (named HCMR after 2002) and participated in many national projects, aiming at the exploration and mapping of active submarine faults in the Greek Seas and applied projects, related to the route surveys for the deployment of underwater pipelines and cables. During his 25-year career at HCMR he has participated in and co-ordinated over 50 national funded projects and applied surveys. He was also primary investigator in more than 18 European funded projects with main objectives relevant to sedimentology and geophysics, Holocene geology, seismic stratigraphy of Late Quaternary sediment sequences of deep basins, geotechnical properties of sediments, slope stability, cold seeps and mud volcanoes.

Dr Grigoris P. Rousakis has significantly contributed to the progress achieved by HCMR through his involvement as member in all committees responsible for the implementation of development projects of the Centre. Moreover, he has been involved either as chief scientist or as head of the marine geology-geophysics group in search and recovery surveys/operations of maritime accidents or aircraft/helicopter crashes at the sea.

Dr. Grigoris P. Rousakis completed his doctoral thesis at the Section of Geological Sciences, Department of Mining and Metallurgical Engineering of National Technical University of Athens, Greece in 2005, focusing on the potential relationship between the sedimentological and geotechnical properties, the sediment accumulation mechanisms and the factors control sedimentation processes in deep basins and margins of the N. Aegean Trough and N. Skyros basin Greece.

Since his promotion to Associate Researcher in 2006 he has widened his expertise including the research fields of paleoceanography/ paleoclimatology and marine geoarchaeology. Because of his long experience in applied projects and his ability to use state of the art techniques and improve standard methodologies he is being considered as expert in marine geological, geophysical and geotechnical surveys related to deployment of cables, pipelines and artificial reefs and offshore windparks
