Dr George Petropoulos
George P. Petropoulos completed his graduate studies (MSc, PhD) at the University of London in 2008, specialising in Earth Observation (EO) Modelling, focusing specifically in the retrievals of energy fluxes (latent & sensible heat fluxes) & soil moisture from the synergy of optical (VNIR & TIR) EO data with simulation process models. A variant of the methodology he investigated during his PhD has been proposed for deriving operational estimates of soil moisture by NPOESS/NASA Space Agencies in downscaling the European Space Agency's (ESA's) operationally distributed soil moisture product provided today by their SMOS satellite.
After completing his PhD, George worked for 1.5 years as a postdoctoral fellow at Bristol University (UK), focusing principally on the exploitation of EO data in post-fire hazard assessment. Since then, & until the end of 2011, he worked in Greece as a research fellow supporting research & teaching activities in a variety of institutions & R&D projects, in some of which he was the coordinator (PI) himself. His last position prior to joining the DGES was a Postdoctoral Research Fellow of the European Space Agency (ESA) based in Greece. At present, as a Senior Lecturer in DGES he also holds a Marie Curie Fellowship from the European Commission (2013-2017).
Dr. Petropoulos serves as a Council member of the Remote Sensing & Photogrammetric Society (RSPSoC), Editorial Board Member on several international peer-reviewed scientific journals in EO & environmental modelling & as a reviewer for various funding bodies (including the European Commission). He is also responsible for the global distribution & maintenance of the SimSphere l& biosphere model from DGES & also for the in-situ soil moisture monitoring network "Wales Soil Moisture Network (WSMN)". He has also convened the organisation of several scientific sessions at international conferences (+10 so far) & of special issues (+3 so far) to scientific journals. He is Editor/Co-editor of 2 books so far (for Taylor & Francis & Elsevier), author/co-author +50 peer-reviewed journal articles (a total sum of >140 impact factor points), +90 international conferences. He has developed fruitful collaborations with key scientists in his area of specialisation globally, & his work so far has received international recognition via several significant awards he has obtained.
