Dr. Papakonstantinou is an Assistant Professor in Cartography and Geoinformatics at the Department of Civil Engineering and Geomatics, School of Engineering and Technology at the Cyprus University of Technology. He holds a Ph.D. in the field of "Cartography & Geoinformatics" with a specialization in Scale issues in Geovisualization from the Department of Geography, University of the Aegean, an MSc in "Cultural Informatics and Communication" from the Department of Cultural Informatics and Communication, University of the Aegean and a degree in Physics from the University of Ioannina.

His main research interests focus on Cartographic Visualization and Geovisualization using Drones for 2D and 3D mapping of spatiotemporal phenomena. He is researching data acquisition pipelines and visualization methodologies using drones and various airborne sensors for (a) illustrating spatial and/or spatiotemporal patterns and (b) mapping environmental phenomena emphasizing ον 2D or 3D Geovisualizations and cartographic products. Additionally, he is investigating the use of RGB, multispectral and hyperspectral cameras, and LiDAR sensors operated from lightweight platforms to visualize various phenomena at different scales.

His work combines computational methods and machine learning algorithms for automatically detecting and mapping changes in the coastal zone and using Augmented Reality and Virtual Reality in Geovisualization.

Dr. Papakonstantinou was a postdoctoral research fellow funded in 2016 and 2019 by the Greek State Scholarships Foundation (IKY) for research on a) the "Detection and Mapping Marine Plastic Litter in the Coastal Zone using Unmanned Aerial Systems and Deep Learning Techniques” and b)"The potential use of UAS (Unmanned Aerial Systems) for the Geovisualization and mapping of coastal environments».

He has more than 90 publications in peer-reviewed international journals and international conferences, chapters of books, and Atlases. He was the cartographic editor of the "Atlas of the Greek Islands" and in a large number of maps for research projects.

Furthermore, he has been involved in many research projects as a senior expert in cartography and geoinformatics at the Cyprus University of Technology, the Aegean University, and the International Hellenic University.

He serves as a reviewer for the following international journals: ISPRS - International Journal of Geoinformation, MDPI – Remote Sensing, Drones, Geosciences, Sensors, Sci, Sustainability Journals, Springer - Applied Geomatics, Reports on Geodesy and Geoinformatics.
