My research focuses on developing smart digital twins for urban environments, integrating geospatial AI, remote sensing, and 3D data science. The work is structured around three major verticals.

I focus on twin attribution and feature extraction using high-resolution remote sensing data, including imagery and LiDAR. This involves semantic segmentation, object detection, and attribution of key urban features critical for downstream planning and analysis.

I work on the development of digital twins using learning and optimization techniques, particularly deep learning applied to 3D representations such as point clouds, meshes, and depth maps. My research explores accurate 3D data generation, as well as transformations across different 3D formats to enable interoperability and flexibility in simulation environments.

I emphasize synthetic 3D representation generation using multimodal data sources. This includes the automatization of large-scale outdoor 3D maps using deep generative models trained on aerial, street-view, and ground-truth data.

I apply these smart digital twins to diverse use cases, including urban planning, climate resilience, and simulation environments for autonomous systems. My goal is to build scalable, transferable models that support intelligent decision-making in complex urban settings.
