Dr. Gregoriou is the Director and Chairman of the Board at the National Hellenic Research Foundation (NHRF).  Dr. Gregoriou is an internationally known scientist with research and managerial positions in both Greece (NHRF, FORTH-ICEHT) and the US (Advent Technologies, Northeastern, MIT, Polaroid, Princeton) over his 25 year research career so far. 

His research activity extends over a wide area of subjects that include the areas of flexible photovoltaics based on organic semiconductors, optically active materials based on conjugated oligomers and polymer nanocomposites.  Previous subjects included the characterization of polymeric liquid crystals, the orientation characteristics of ionic polymer multilayers on patterned self-assembled monolayers and the subject of chemometrics.  He is the coauthor of 3 books, 6 chapters in books, 69 refereed research papers and 133 research presentations and the co-inventor of 8 patents. 

His academic teaching experience spans in both undergraduate level in the US (University of Massachusetts) as well as at the graduate level in both the USA  (University of Connecticut) and Greece (University of Patras).  He has also served as the President of the Society for Applied Spectroscopy (SAS) in 2001.

Dr. Gregoriou is also the Greek National Representative in the Horizon 2020 Committee for the European Research Council (ERC), the Mari Sklodowska-Curie actions, and the Future and Emerging Technologies (FET). Horizon 2020 is the biggest EU Research and Innovation program ever with nearly €80 billion of funding available over 7 years (2014 to 2020). The ERC's mission is to encourage the highest quality research in Europe through competitive funding and to support investigator-driven frontier research across all fields of research, on the basis of scientific excellence. A total budget of 13 095 million euro is available for the implementation of the ERC funding schemes under Horizon 2020.
