Dr. Anastasios (Tasos) Anastasiadis was born in Thessaloniki, Greece, in 1964. He received the B.Sc. in Physics from the Aristotle University of Thessaloniki, Greece (1986) and the Ph.D. in Astrophysics from the same University (1994). He has worked as Research Assistant at the Section of Astrophysics, Astronomy and Mechanics, Department of Physics, University of Thessaloniki (1995 – 1998), as Associate Researcher (1998 – 2001) and Principal Researcher (2002 - 2007), at the National Observatory of Athens. He is currently Research Director at the Institute for Astronomy, Astrophysics, Space Applications & Remote Sensing (IAASARS) of the National Observatory of Athens (NOA) (since 2008). He is a member of the Space Research & Technology Group of IAASARS/NOA and a team member of the HellENIc GeoMagnetic Array (ENIGMA). He was co-teaching, during the first semester, the course on "Space Environment" in the program Master of Science in Space Science Technologies and Applications (2017-2020).

He is a member of the International Astronomical Union (IAU), of the European Astronomical Society (E.A.S.), of the European Geosciences Union (EGU), of the Hellenic Astronomical Society (Hel.A.S.), of the Community of European Solar Radio Astronomers (CESRA). He was elected board member of Hel.A.S. (2010 - 2012 & 2012 - 2014).

He is a member of the Modelling and Data Analysis Working Group (MADAWG) for the ESA/Solar Orbiter mission. He is a member of the COSPAR International Space Weather Action Teams (ISWAT). He has received the ESA/Science Individual Award for his outstanding contribution to the ESA Rosetta Mission.

His scientific interests include High‐energy phenomena in Space Plasma Physics and Plasma Astrophysics; Transport, Diffusion and Particle Acceleration processes in Heliophysics; Sun ‐Earth connection processes; Solar Flares and CMEs; Solar Energetic Particle Events; Space Radiation Environment; Space Weather; Radiation Belts Dynamics; Magnetospheric Physics; Non-linear Dynamics; Complexity; Machine Learning Techniques.

He has published more than 80+ refereed scientific papers in international journals and special volumes/books and more than 25 papers in conference proceedings. His work has received more than 1700 citations, h-index 24 (see Google Scholar and Researcher-ID).

He served as a Guest Editor for the "Journal of Atmospheric and Solar-Terrestrial Physics" (2001), the journal "Entropy" (2010 - 2011) and the "Journal of Space Weather and Space Climate" (2019). He is a member of the Editorial Board of the journals "International Review of Physics" and "Entropy".

He served as reviewer for the following journals: The Astrophysical Journal, Astronomy and Astrophysics, Journal of Atmospheric and Solar-Terrestrial Physics, Journal of Geophysical Research, Annales Geophysicae, Geophysical Research Letters, Advances in Space Research, Natural Hazards and Earth System Sciences, Journal of Engineering Science and Technology Review, International Journal of Modern Physics –D, Earth Moon and Planets, Nonlinear Processes in Geophysics, Physica A: Statistical Mechanics and its Applications, Frontiers in Astronomy and Space Sciences, Journal of Space Weather and Space Climate, Entropy and Space Weather.
