Dr. Christos Maravelias is Director of Research in the Institute of Marine Biological Resources (IMBR) of HCMR.

Dr Maravelias joined HCMR as a senior scientist in 2006. Before that he has been a Lecturer in the University of Thessaly, Magnesia, Greece from 2000-2005. He has supervised numerous research theses and dissertations and published more than 80 publications in peer-reviewed journals, congress proceedings and books. He has a 20 years of high-level hands-on experience with international scientific collaborations through numerous European projects, scientific working groups, data collection/analysis, and evaluation and impact assessment of alternative management strategies in Mediterranean fisheries.

He has been the Fisheries Expert of the 7th Framework Programme of the European Commission (EC) in the Directorate General for Research and Technological Development (DG RTD) in Brussels. Since 2000 has been acting as an independent Expert Consultant for the European Commission, DG XIV Fisheries (now MARE) for progress monitoring of approved FP5 and FP6 research programs in the fields of Fisheries Management + Interactions / environment as well as Policy Oriented Research. Furthermore, since 2000 he has been an Evaluator of research projects’ proposals submitted under FP5, FP6 and FP7 programmes for the European Commission.

Dr Maravelias has a thorough knowledge of the EU policies and fisheries sector, the CFP and Framework Programmes from his work in DG RTD in Brussels as FP7 Scientific Programme Officer. Through his work in the European Commission he has had the opportunity to be involved in numerous committees, working groups and meetings with public and private institutions, professional bodies of the Member States and others dealing with fisheries and seafood issues. The most relevant are: the European’s Commission Committee for the preparation of European’s Union Maritime Research Strategy Communication, the EC Committee for the preparation of European’s Union Strategic Plan for Fisheries, the EC Inter-Service Steering Group for the preparation of the Impact Assessment for the Joint Baltic Sea Research Programme (BONUS-169), the European’s Commission Committee for the preparation of European’s Union Plan of Action for the Conservation & Management of Sharks. For the above Commission papers and communications finally produced, Dr Maravelias provided scientific input.

Dr. Maravelias holds a Ph.D degree in Fisheries Biology from the University of Aberdeen, Scotland (United Kingdom), a M.Sc degree in Fisheries Biology and Management from the University of Wales, Bangor (United Kingdom) and a B.Sc degree in Biology from the Aristotle University of Thessaloniki (Greece).
