Dr. Kang is researcher and engineer specializing in the convergence of Civil Engineering, Computer Vision, CAD, and advanced Software Engineering for Digital Transformation (DX). As a Research Fellow at the Korea Institute of Construction Technology (KICT), the research focuses on Digital Twin technology, advanced BIM-GIS integration, and computational geometry solutions. He leads the international standardization effort for ISO 19166 (BIM-GIS conceptual mapping). Dr. Kang possesses extensive practical experience in software development, spanning the full engineering lifecycle. His achievements include implementing a high-performance CAD engine for large Digital Terrain Models (DTM), and developing 3D Scan to BIM, BIM-based core systems such as Building Energy Management Systems (BEMS) and Facility Management (FM) solutions. He has successfully created Vision-based reverse engineering engines and Robotics Operating System (ROS) solutions for advanced Scan-to-BIM workflows, applying deep knowledge of 2D/3D Geometry Computation and Spatial Indexing. Driving the future of smart construction, Dr. Kang actively incorporates advanced AI and Deep Learning techniques, including 3D Vision, SLAM, and cutting-edge NLP applications like Large Language Models (LLM), RAG, and AI Agents. Furthermore, he is a dedicated Technical Author and has co-authored over ten (10) professional
