Maria Petropoulou, born in Athens in 1985, completed her undergraduate studies in Physics at the National and Kapodistrian University of Athens (NKUA) in 2008. She obtained a MSc degree in Astrophysics, Astronomy and Mechanics in 2010 and a PhD degree in Physics in 2014, both from the Department of Physics of NKUA. She received the prize for the Best PhD Thesis from the Hellenic Astronomical Society in 2015 and the Fondation MERAC in 2016. In 2013 she was selected by NASA as one of the 12 Einstein Postdoctoral Research Fellows of that year. She worked as an Einstein Fellow (2013-2016) and a Postdoctoral Research Associate (2016-2017) at the Department of Physics and Astronomy of Purdue University, West Lafayette, Indiana, USA. She then moved to the Department of Astrophysical Sciences at Princeton University, New Jersey, USA, where she worked as Lyman Jr. Spitzer Postdoctoral Fellow (2017-2020). She joined the Department of Physics of NKUA in 2020 as Assistant Professor. Her research interests lie in the field of high-energy and multi-messenger astrophysics and include radiative processes in astrophysical plasmas, particle acceleration processes, cosmic-ray and neutrino production processes. She has published 59 articles in peer-reviewed journals with high impact factor and she has given more than 30 invited talks in international conferences and workshops. She is a member of the Hellenic Astronomical Society (HelAS), the European Astronomical Society (EAS), the American Astronomical Society (AAS), and the High-Energy Astrophysics Division (HEAD) of AAS.
