I am a marine microbiologist and my current research interests focus on: (i) the study of taxonomic and functional diversity of the water column; (ii) symbiotic microorganisms of marine fishes and inverterbarates.

• Microbial diversity in marine habitats using novel molecular techniques.
• Changes of fish microbiome reared under changing conditions or after the use of different feeds.
• Microbial taxonomic and functional diversity in extreme environments.

Undergraduate level: Biology, Marine Microbiology, Microbiological Quality Control of Fishery Products and Food (University of the Aegean).

Graduate level: Participation in Host-Microbe Interactions (HosMic), Interdisciplinary M.Sc. program, teaching to modules, Bioinformatics for Microbiomes and Animal-Microbe Interactions (University of Thessaly).
