Giokas Sinos

• BSc, Department of Biology, National & Kapodistrian University of Athens (1988)
• PhD, Department of Biology, National & Kapodistrian University of Athens (1996)

Courses:

• Undergraduate courses: i) Animal Biology I, ii) Ethology, iii) Biogeography, iv) Biodiversity & Conservation Biology.
• Postgraduate courses: i) Sampling, Data Analysis & Ecological Models, ii) Biodiversity Assessment and Biomonitoring of Species & Habitats.

Supervisions:

• Supervision of 7 PhD, 17 MSc and 28 undergraduate theses.

• My research focuses on the relationship between ecological and evolutionary processes. Specifically, my research interests include: (1) the study of the evolutionary ecology of terrestrial animals, focusing on their phylogeny and the processes of their speciation and differentiation, as well as their behavioral, morphological, ecological, physiological and population adaptations, (2) the investigation of the biodiversity patterns of island and continental animal communities and the processes that shape them.
• I have extensive experience in: (1) Ecological field research. Since 1987 I have participated in numerous in numerous expeditions to collect biological material in mainland Greece, and in more than 80 islands and islets of the Aegean and Ionian Seas, (2) in the generation and analysis of molecular, ecological and morphological data.
• I have participated in 40 research projects of the Departments of Biology of the Universities of Athens, Crete and Patras. I was Scientific Leader in 20 of them.
