Short CV

  • BSc in Biology, Department of Biology, University of Crete (1987-1991)
  • MSc in Marine Biology, Department of Biology, University of Crete (1991-1993)
  • PhD in the Laboratory of Fisheries Biology, Department of Biology, University of Crete (1994-1999)

Dr. Somarakis assumed his duties on January 2008. He was a Lecturer in the Biology Department of the University of Patras from 2002 to 2006 and Assistant Professor in the Biology Department of the University of Crete in 2007.

He is an expert on ichthyoplankton, egg production methods, larval fish ecology, fish reproduction and pelagic food webs, with long experience on small pelagic fish and fisheries.

He has participated in more than 55 national and international projects.

He was chairman (2005-2008) of the Working Group on small pelagics of the General Fisheries Council for the Mediterranean (GFCM-Scientific Advisory Committee) and Coordinator of the Sub-regional Committee for the Adriatic Sea (SRC-AS/GFCM) in 2016. He is a member of the Scientific Technical and Economic Committee for Fisheries (DG MARE) since 2003.

He is the Editor-in-chief of the ‘Mediterranean Marine Science’ journal and serves on the Editorial Board of ‘Marine Ecology Progress Series’ and ‘Scientia Marina’.

He supervise(d)s 10 MSc and 3 PhD theses and co-supervise(d)s9 PhD theses.

He has contributed 110 papers in peer-reviewed journals (up to 2021), 16 book chapters, as well as more than 150 other publications (i.e., conference proceedings, special publications, newspaper and magazine articles).
