Dr. George Kontakiotis achieved a Ph.D. degree in Paleoceanography in 2012 at the National and Kapodistrian University of Athens (NKUA), where he later worked as Laboratory and Teaching Staff in the fields of Marine Geology and Sedimentology, and recently as Associate Professor of Sedimentology–Paleoceanography–Chemostratigraphy in NKUA. His major research contributions include developing novel approaches on the distribution and pathways of diagenesis in Mg/Ca paleothermometry. He has further worked on sedimentological and paleoceanographic reconstructions at different time scales by means of marine cores and land sections. His main research topics are summarized as follows: environmental sedimentology; marine petroleum systems; exploitation of natural energy resources; microfacies analysis; sequence stratigraphy; integrated bio-cyclo-tephro-stratigraphy; carbonate and clastic reservoirs; calibration–validation–application of geochemical proxies for sea surface temperature (SST) and salinity (SSS); applied en
