We are a research group based in the College of Computing and Data Science, Nanyang Technological University. We focus on the research, design, and evaluation of networked, energy-efficient, and secure sensing systems found in the Internet of Things (IoT) and its AI-empowered generation (AIoT). Our research has two main sub-directions of IoT sensing systems/applications and security/privacy of AIoT sensing. In the first sub-direction, with a strong experimental focus, we study a number of sensing modalities (e.g., powerline radiation, acoustics, image, thermal, and energy), exploit them to construct system functions and applications. In the second sub-direction, we study the security and privacy of AIoT sensing systems that use machine learning and modern AI to process the sensed data. Our research primarily follows the cyber-physical system (CPS) methodology that addresses the coupling between the cyber and physical subspaces of the studied system. Due to the immediate application potentials, our research has been funded externally by government authorities and companies in the infocomm, energy, and manufacturing sectors.
