Athanasios Naskos

I was born in Greece in 1988. I graduated the Computer Science Department of the Aristotle University of Thessaloniki, Greece in 2011. I received the M.Sc. in Computer Science from the same institute in 2013. I received my Ph.D. in Computer Science in 2017. My research interests lie in the field of cloud elasticity, distributed data management and model checking.
