My name is Junjie Chen. I am currently a Postdoctoral Fellow in the Department of Real Estate and Construction at HKU. I obtained my PhD in hydraulic engineering from Tianjin University in 2020, and has been a visiting researcher at the University of Tennessee, Knoxville from 2018 to 2019. My research covers a broad area in construction informatics and built environment: Building Information Modeling (BIM), Computer Vision, Machine Learning, Intelligent Compaction, and safety management of water supply infrastructure. I am particularly interested in exploiting the latent value of low-cost visual assets (dynamic video or static images; virtual renderings or photorealistic) in the AECO industry by the use of advanced machine learning techniques.
