Petros Pistofidis is a Researcher, Software Engineer and Lecturer with more than seventeen years bridging full-stack development with academic teaching and research. He currently serves as Research Associate at the Athena Research and Innovation Center and Adjunct Lecturer at the Department of Production Engineering and Management, Democritus University of Thrace (DUTH). His work sits at the intersection of industrial informatics and human-centric computing, organised around three interconnected strands. The first explores how IoT, AI and Industry 4.0/5.0 technologies can support reliability engineering, predictive maintenance, and occupational safety (typically with humans in the loop). The second focuses on IoT/IIoT-coupled 3D digital twins, including web and cloud-based annotation tools that fuse sensor data with spatial models of physical assets. The third addresses educational technologies, vocational training, and digital accessibility, drawing on HCI and ergonomics.
