Ir. D. G. Rangelov MSc | People Pages: Find employees & contact details

I am a researcher at the intersection of computer science, 3D imaging, and artificial intelligence, with a particular focus on forensic applications. In my role as a guest PhD candidate at the University of Twente, I investigate how advanced reconstruction techniques, such as neural rendering, Gaussian splatting, and photometric stereo, can be employed in crime scene analysis under challenging conditions like variable lighting. My expertise spans 3D reconstruction, imaging in adverse conditions, and AI to support forensic investigation workflows.

Within the Technologies for Criminal Investigations (TCI) research group, I lead the CrimeBots research line, which focuses on the integration of robotics, sensing technologies, and artificial intelligence in the context of crime investigation, security, and safety. Our work bridges the gap between research and practical application, developing innovative robotic systems, 3D reconstruction methods, and AI-driven tools to enhance the efficiency, reliability, and ethical use of technology in real investigative environments.
