Curriculum Vitae


I received my B. Sc. in Physics (2005), my M. Sc. in Nuclear & Particle Physics (2007) and my Ph.D. in Physics (2012) by the Department of Physics of the National & Kapodistrian University of Athens, Greece.

Since then I worked as a Post-doctoral Researcher at the Institute for Astronomy, Astrophysics, Space Applications and Remote Sensing (IAASARS) of the National Observatory of Athens and at the National & Kapodistrian University of Athens. I have been a Visiting Researcher at the Christian-Albrechts-Universitat zu Kiel (Germany), the University of Turku (Finland) and the Institute of Terrestrial Magnetism, Ionosphere and Radiowave Propagation by N.V. Pushkov RAS (IZMIRAN) (Russia).

In 2018 I was elected as an Associate Researcher at IAASARS/NOA .

I have co-authored 46 papers published in refereed journals which have received ~930+ citations, h-index=18 (source Google Scholar). A complete list of my papers is available here.

My brief CV is available as a PDF file here, while an extended CV can be found here. My ResearcherID is K-7065-2013 and my Google Scholar record is here .
