Education

  • 2010: Ph.D in Biological Sciences, School of Biological Sciences, University of Aberdeen, U.K.
  • 2003: M.Sc in Oceanography, School of Ocean and Earth Science, University of Southampton, U.K.
  • 2002: BSc (Honours) in Biology, Department of Biology, School of Natural Sciences, Aristotle University of Thessaloniki, Greece.

Research Interests

My research interests focus on the marine carbon cycle and particularly on the degradation of organic matter by marine microorganisms. I am interested in the biodegradation of crude oil at sea and the effect of hydrostatic pressure on the composition and function of deep water hydrocarbon-degrading microbial communities as well as the improvement of bioremediation strategies to treat oil spills.  An additional field of my research is the degradation of terrestrial plant cell walls in the marine environment and the degradation enzymes produced by marine microorganisms, which find applications in modern biorefineries for the production of chemical compounds and biofuels.
