Other activities

He is among the top 2% of scientists worldwide in Image Processing, based on Scopus standardized citation metrics from Stanford University https://elsevier.digitalcommonsdata.com/datasets/btchxktzyw). He is an author of more than 50 several refereed papers in international scientific journals and books, member of editorial board of Remote Sensing (MDPI) and Mediterranean Marine Science Journals, referee in several scientific journals and principal investigator in international research projects. Prior to his academic career he worked for the European Commission Joint Research Centre, ISPRA, Italy and in Greek private sector.

He lives in Lesvos island with his wife Elli and their two boys Nicolas and Dimitris. He is a qualified sailing skipper, but deep down he wishes he could have been a professional sailor.
