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 Postdoctoral 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), the Institute of Terrestrial Magnetism, Ionosphere and Radiowave Propagation by N.V. Pushkov RAS (IZMIRAN) (Russia), the Universitat de Barcelona (Spain) and the European Space Astronomy Center (ESAC) (Spain).

In 2018 I was elected as an Associate Researcher and in 2021 I was promoted to a Senior Researcher at IAASARS/NOA .

I have co-authored 67 papers published in refereed journals which have received ~2200+ citations, h-index=29 (source Google Scholar). A complete list of my papers is available here.

My researcherID is K-7065-2013, my ORCID is 0000-0002-9479-8644 and my Google Scholar record is here. Github repositories are provided here .
