My research activities are related to the study of dynamics of coastal marine ecosystems emphasizing on (a) phytoplankton ecology and diversity, (b) water quality assessment, (c) integrated coastal zone management, using numerical simulations and statistical methods. This research results to (a) publications in peer-reviewed journals and announcements in scientific conferences, (b) supervision of PhD, MSc theses and dissertations, (c) participation in research projects and (d) scientific collaborations in national and international levels. The recognition of my work (Web of Knowledge, March 2019) is summarized into 821 citations (excluding self-citations), average of 22.41 citations per article and h-index of 15.


At the undergraduate level, I offer mandatory courses on 'Introduction in Informatics and Programming', 'Simulation Methods and Applications', as well as optional courses on 'Numerical Analysis' and 'Models in Ecology'. At the postgraduate level, I offer lectures on 'Quantitatve analysis of Environmental data' in the framework of the M.Sc. Programs on 'Integrated Coastal Zone Management' and 'Research in Marine Sciences' coordinated by the Department of Marine Sciences and 'Research in Environmental Sciences' coordinated by the Department of the Environment.
