Olga Sykioti obtained her BSc in Geology from the University of Athens in 1988. She obtained her MSc in Remote Sensing (1990), MSc in Hydrology, Geostatistics and Geochemistry (1991) and her PhD in Geosciences and Remote Sensing (December 1994) from Pierre & Marie Curie University (Paris, France).
From 1995 to 2000 she worked in as image processing and photogrammetry specialist in the private sector and in parallel as postdoctoral researcher at the National Observatory of Athens (1999-2000). In 2001 she started working as scientific staff till 2006, when she was elected Assistant Researcher in the former Institute for Space Applications and Remote Sensing of NOA. In 2011 she was promoted to an Associate Researcher and in 2017 to a Senior Researcher.
