I am a chemist, with a specialization in analytical and environmental chemistry. I obtained my PhD degree in Environmental and Water Resources Engineering, having worked on pesticide degradation in drinking water via the UV/H2O2 process. I have acquired an in-depth knowledge of water chemistry, radical and oxidation chemistry, photo-chemistry, water treatment processes and especially Advanced Oxidation Processes (AOPs) regarding the degradation of micro-pollutants. I have lived and worked within research teams in Greece, United Kingdom and the Netherlands, in multi-cultural and multi-disciplinary environments. I have trained and supervised three students, two for Master thesis and one for internship purposes. Currently, I am a PostDoctoral Researcher at the SoWa Department of the Biology Centre CAS in České Budějovice (Czech Republic) and a member of Travis Meador’s team. My work at SoWa will mainly involve the study of degradation pathways and turnover of carotenoids in order to investigate their diagenetic products and their potential to serve as biomarkers of recalcitrant organic matter in aquatic systems.
