Research interests
My research focuses on the integration of geospatial technologies such as LiDAR/Laser Scanning, photogrammetry, GNSS, and UAV-based mapping to support high-resolution 3D modeling and spatial analysis. I am particularly interested in Building Information Modeling (BIM) and Digital Twin development for infrastructure, cultural heritage, land administration systems and smart city applications, with an emphasis on real time 3D geovisualization in virtual and web based platforms like CesiumJS and X3DOM.
