Short CV

  • BSc in Natural Resource Conservation, School of Natural Resource Conservation, University of Florida, USA (1994)
  • MSc in Natural Resource Conservation, School of Natural Resource Conservation, University of Florida, USA (1996)

He has attended special training courses in Geographic Information Science, Remote Sensing and Aquatic Sciences (Fisheries, Oceanography) at the Schools of Geography, Zoology, and Ocean Engineering of the University of Florida, USA.

In 1997, he joined the Institute of Marine Biology of Crete (Greece) as GIS research scientist, participating in research projects and since 2002, he is a member of the research staff of the Hellenic Centre for Marine Research (HCMR) coordinating and participating in projects. with European and National funding. Up to 2013, he coordinated 3 European-funded projects and participated in another 13 projects with a total budget for coordinated or scientific responsibility funding of more than 1MECU.

He has research interests on the application of GIS and Remote Sensing in Aquatic Sciences, depicted in one authored book and numerous special issues (see

He is a member of the scientific and organizing committee of the triennial Int’l Symposium of GIS and Spatial Analysis in Aquatic Sciences. He is Associate Editor of Hydrobiologia (Springer) and a member of the editorial board of Scientia Marina.

Up to 2013, he has contributed more than 125 publications. For a complete publication record and other relevant information, visit Valavanis profile.
