We conduct research on construction engineering and management (CEM), focusing on 1) how to better understand human behavior using IT-oriented approaches, and 2) how to better design IT systems based on in-depth understanding on the interaction between human and IT systems. IT-oriented approaches and systems we are interested in include but not limited to computer vision, wearable sensing, VR and AR etc. Ultimately, we aim to contribute to the industry by providing IT-based solutions to handle productivity, safety and health issues in construction while we try to expand the body of knowledge through scientific research in CEM.
