Olga E. Malandraki obtained her BSc degree in Physics from the University of Athens (1993) and her PhD in Space Physics from the Democritus University of Thrace in Greece (2002, Division of Space Physics and Telecommunications).

From 2002 until 2005 she was a Postdoctoral Research fellow in the Institute for Space Applications and Remote Sensing of the National Observatory of Athens (NOA) and the Democritus University of Thrace. She was a Post-doctoral Research Fellow of the Greek National Foundation (IKY) for the period 2003-2004. From 2005 until 2007 she was an Internal Research Fellow in the Research and Scientific Support Dept. of the European Space Agency (ESA) at ESTEC in the Netherlands. In 2005 she was a Research Associate of the Univ. of Athens and from 2007 until 2008 she was a Research Associate of the Space and Armos. Physics Group at Imperial College, London in the UK. Since 2007 she is a permanent scientific staff member of the IAASARS of the National Observatory of Athens. She has performed extensive research collaborations abroad and has been an Invited Visiting Researcher in the Naval Research Laboratory, Space Sci. Division, USA, the Goddard Space Flight Center at NASA, the Christian-Albrechts-Universitaet zu Kiel, in Germany, the Observatoire de Paris, Meudon, in France, the Bell Laboratories, Lucent Technologies, in the USA. She has received the ‘GROUP ACHIEVEMENT AWARD TO ULYSSES MISSION TEAM’ by NASA and the ‘ULYSSES ACHIEVEMENT AWARD – 15 YEARS IN ORBIT’ by ESA, Science. She has been an ‘Expert’, Member of Representative team of Greece to ESA/SPC since 2010, an Organizing Committee Member, of the International Astronomical Union, Division E, Commission 49 since 2012, Scientific Officer on ‘Heliosphere’ of the European Geosciences Union (EGU) since 2011, National Co-ordinator, International Space Weather Initiative of the United Nations since 2010 and Spokesperson, of the ESA Space Weather Working Team (SWWT/TWG 2) since 2012. She has been Scientific Responsible for NOA for the ‘SEPServer’ and ‘COMESEP’ FP7 projects since 2010.
