Teaching and Research Statement


Dr. Lai has been working on nondestructive and geophysical imaging and diagnosis of underground utility networks and concrete infrastructures. His main teaching and research interests include survey & mapping, 3D imaging, and diagnosis of engineering structures, underground utilities, construction materials, hydro-geophysics, and sites of archaeology values. These techniques include ground penetrating radar, infrared thermography, acoustic, ultrasound, acoustic leak noise correlation, laser scanning, flow monitoring, etc. Dr. Lai designed the first-of-its-kind and 25,000 sq.ft. underground water mains’ leakage training centre ‘Q-Leak’ for Water Supplies Department (WSD) of HKSARG on 2020-21[1], in which a MoU was signed on Nov 2021 for subsequent collaboration between PolyU and WSD. From 2018-2021, he is funded by ITF to chair a 40+ people strong steering/international/technical committees of underground utilities for formulating a set of six utility survey specifications[2]. They are now recognized by HK Accreditation Services as the basis (HOKLAS SC55)[3] for accrediting commercial laboratories conducting such services. (As of Feb 2022)
