Paruyr Sergey Efendyan serves as Professor in the Department of Cartography and Geomorphology at Yerevan State University's Faculty of Geography and Geology since 2020, with prior institutional memberships at YSU (2021-2023) and Armenian National Agrarian University (2009-2023). His academic foundation includes a Certified Specialist degree in Urban Construction from Kiev Engineering and Construction Institute (1969-1974) and postgraduate studies in Applied Geodesy at Moscow Institute of Geodesy and Cartography (1982-1987), culminating in a 2016 Doctor of Science degree from Armenian National Agrarian University for research on Armenia's unified land information system. Professor Efendyan's research centers on Geodesy, Land Construction, and Cadastre, addressing critical challenges in spatial data infrastructure, land valuation methodologies, and geodetic applications for earthquake monitoring and agricultural land management. His work bridges historical land survey practices with modern technological solutions. His 2022-2025 publications reveal strong thematic cohesion around national spatial data infrastructure development, with recurring emphasis on AI integration, legal frameworks, cadastral revaluation, and satellite-based topographic mapping. Key trends include Python-based quality control systems for road data and anthropogenic impact analysis on soil composition. He actively participates in international forums including Geoforum-2023 (Ukraine), Environmental Protection conferences (Russia, 2022), and Land Management summits (Kyrgyzstan, 2021), demonstrating global engagement despite no explicitly listed scientific awards. Professor Efendyan advises students and manages research grants focused on Armenia's spatial data infrastructure modernization, particularly through Python-based quality control frameworks for road network datasets, though specific grant details remain unlisted in available materials.
