Research
Dr. Konstantinos Topouzelis is an Associate Professor in the Department of Marine Sciences, University of the Aegean and he heads the Marine Remote Sensing Group. He holds a Bachelor's degree in Environmental Studies (University of the Aegean, Department of Environment), a Master's degree in Remote Sensing (University of Dundee, Department of Applied Physics & Mechanical Engineering) and a Ph.D. in pollution monitoring from space (National Technical University of Athens, School of Rural and Surveying Engineering). .
His main research interest is on the analysis of remote sensing datasets, including satellite and aerial images, for marine and coastal applications. His expertise includes automatic detection of oceanographic phenomena, Object Based Image Analysis, image processing algorithms and coastal mapping.
