I was born in Athens, Greece, but I grew up in a town around 100 km from Athens, namely Orchomenos in Voiotia prefecture. I lived there until 18 years old and then moved to Ioannina city in order to study chemistry at the local university. After the end of the bachelor's degree in chemistry, I attended the Master's program of the National and Kapodistrian University of Athens in the specialisation of Chemistry and Environmental Technology. My treatise was carried out at the Environmental Radioactivity Laboratory (ERL) of the Institute of Nuclear Technology and Radiation Protection of the National Centre for Scientific Research "Demokritos" and the title was "Cesium– 137 horizontal dispersion and vertical distribution in the water column of Corinthiakos and Patraikos Gulf: Determination of activity concentrations using two methods, in comparison". After the Master's program I was selected to carry out a PhD thesis under the same collaboration (University of Athens & NCSR "Demokritos") awarded a 4 year fellowship after outstanding performance in written exams. The thesis (Study on the distribution of radioisotopes and trace elements in the marine environment) was related to the fields of Isotopic Geochemistry and Marine Radiochemistry and was completed in 2010. I worked at the same laboratory for 1 more year as a postdoctoral fellow analysing and measuring samples for the Greek monitoring system where the ERL participates for many years providing support to the decisions of the Greek Atomic Energy Commission. In January 2012, I moved to Paris, France, and worked as a postdoctoral researcher at the Laboratoire des Sciences du Climat et de l'Environnement (LSCE). The LSCE is a laboratory related to the French National Centre for Scientific Research (CNRS), the French Atomic Energy Commission (CEA) and the University of Versailles Saint-Quentin (UVSQ). My work at the LSCE dealt with scientific aerosol modeling of radionuclides and BC emitted after fire events. Since October 2014, I have moved to Oslo (Norway) and currently work as a scientist at the Norwegian Institute for Air Research (NILU) holding an active research position. My work deals with inverse modeling of BC in the North Hemisphere and improvement of the current knowledge of the source inventory of radionuclides after accidental releases.
