Georgios studied for a BSc in Forestry with the Department of Forestry of the TEI of Kavala, Greece (1996-2000). He then studied for an MSc in Resource Management (2001-2002) and a PhD (2002-2007) in Forest Ecophysiology and process-based modelling with the University of Edinburgh. He first joint Forest Research in 2006 as a junior researcher for a period of four years working on modelling climate change adaptation on ecological species suitability and process-based modelling of forest carbon sequestration. From 2010 to 2013 Georgios did his post-doctoral studies at the University of Edinburgh working on modelling soil-plant-atmosphere interaction in Arctic tundra. In 2013 Georgios re-joined Forest Research initially for one year and a half working as Tree Ecophysiologist for the EU project ThermoLiDAR, supporting ecophysiological data collection and process-based modelling. Since February 2015 Georgios is working for the GREENHOUSE project as a Greenhouse gases Research Scientists.
