Catherine Tsangaris is an Associate Researcher at the Institute of Oceanography of the Hellenic Centre for Marine Research (HCMR) working in the field of ecotoxicology with a particular focus on the effects of pollution on marine organisms. She holds a doctoral degree in Ecotoxicology from the University of Athens, Greece, a master’s degree in Environmental Biology from the University of Manchester, UK, and a bachelor’s degree in Biology from the University of Athens, Greece. During her doctoral degree, she carried out research visits at the University of Plymouth and Plymouth Marine Laboratory, UK, through an Erasmus grant. Her research area of interest includes biomarkers of pollutant exposure and effects and bioassays. She has studied physiological conditions, bioenergetics, cellular detoxification mechanisms, oxidative stress parameters, genotoxicity, and endocrine disruption in marine organisms about pollution and environmental stress. She has applied biological effect methods to measure the health of marine organisms in a range of marine ecosystems with different types and levels of contamination.
