I am a field biologist, with expertise in the taxonomy and ecology of a wide range of animal groups, (grasshoppers, butterflies, dragonflies, amphibians, reptiles, birds, mammals). I build up primary biodiversity databases, with a special focus on Mediterranean mountainous ecosystems.
International collaboration, independence, ecological breadth, and a consistent focus on providing solutions to major conservation problems are the four points that depict my research profile.
The last research projects I have initiated concerned the sustainable spatial planning of wind farms without undermining biodiversity goals, the delineation of roadless areas as pristine landscapes of high ecological and aesthetic value that should be preserved as such, and several projects on the conservation of endemic and threatened grasshopper species. I have also recently initiated “apollo” the first voluntary citizen-science scheme for monitoring greek butterflies.
It is my belief that biodiversity conservation and ecological justice are the greatest challenges of our century. Science can provide real answers to our biodiversity crisis-era; we do not have the luxury to do science without implementation and vice versa.
For this reason, I am active as a conservation biologist, attempting to apply scientific findings in practice and to bridge the gap between local and international policymaking. I am a member of several international and national scientific societies and NGOs, having also chaired the Education Committee of the SCB-Europe and having organized the first international summer school on conservation biology for five years.
I am together with Haritakis and we have a lovely daughter, Myrto. If I was not to be a scientist, I would be a musician or a book writer of novels and fairy tales…. Who knows, maybe these dreams will come true one day…

Goal: Contribution to tackling the problem of fragmentation of the landscape and natural ecosystems from new road networks. The project mapped the roadless areas of 50 sqkm in Greece, and produced papers, policy briefs, video, and an online spatial database of roadless areas. It suggested a European legislation on conserving the last roadless areas as wilderness areas where new roads and artificial land expansion should be banned. The social impact of the project was large, and the Prime Minister announced in COP26 (November 2021) the intention of the government to conserve the last large wilderness roadless areas in Greece under the name “untrodden mountains”. ROADLESS project continued through NATLAND project.

Targeted species included large mammals, the otter and the dragonflies. The project suggested establishing a cross-border national park of Aoos between Greece and Albania.

Goal: To assess the impact of the agricultural land abandonment on landscape change, on woody species and bird diversity and conclude to measures that contribute to biodiversity conservation. A common methodology for woody species, landscape structure and bird sampling was applied in Greece, Albania, Bulgaria and Croatia, whilst Austria was involved in landscape analysis. The project provided concrete evidence on the negative impact of land abandonment for biodiversity and the positive role of mild grazing in the mid-elevation former agricultural landscapes.

Paper without Impact Factor.
The current research is conducted in the framework of conservation biology, taking as a case study the reserve of Dadia, in NE Greece. Biological diversity is represented by six biological groups: vegetation, orchids, Orthoptera, aquatic and terrestrial herpetofauna, and small terrestrial birds. The diversity and the ecological structure of the group communities are assessed and analyzed for 36 sites, which represent different habitat types in the Dadia reserve. Five conservation scenarios are constructed to design optimal reserve networks for the conservation of biodiversity. They support the scoring versus approach, the principle of complementarity, of biological representativeness, of environmental representativeness, and finally the random design of reserve systems. Their efficiency is tested and their utility is discussed. The degree of coincidence of hotspots and of the optimal network for different groups is measured, as well as the surrogate value of each studied group as a shortcut for the conservation of the other groups and of overall biodiversity. Finally, we discuss practical conservation issues for the reserve of Dadia.
