Konstantinos A Kormas

PeerJ Editor, Author & Reviewer

Summary

I completed my Biology BSc (1994) and PhD (1998) on marine ecology at the National and Kapodistrian University of Athens, Greece. I worked as a post-doctoral investigator on coastal Cyanobacteria at the Trondhjem Biological Station, Norway (2000) and at the Woods Hole Oceanographic Institution, USA (2000-2002) on deep-sea microbiology. In March 2005 I was appointed as faculty of aquatic microbial ecology at the Department of Ichthyology & Aquatic Environment, University of Thessaly, Greece. Since March 2015 I am a full Professor at the same department.
Our research group investigates processes that are related the distribution and abundance of microorganisms in different aquatic habitats and also aquatic animal-microbe interactions.
