My research focuses on information, sensing, and computing technologies for construction and infrastructure systems, construction productivity, and construction safety. I have worked on a set of research projects that have explored several important topics within these areas. These topics include automated data collection and processing, real-time spatial information acquisition and modeling for safer and more efficient construction, video intelligence for jobsite monitoring, identification and localization of engineered components through radio frequency identification (RFID) and global positioning system (GPS), Non-Destructive Testing for infrastructure inspections, and construction productivity breakthroughs through technological advances. Most of these projects are funded by agencies like National Science Foundation (NSF), National Institute of Standards and Technology (NIST), State DOTs, and Construction Industry Institute (CII).


In working on these projects, I have been fortunate to have had opportunities to collaborate with different funding agencies and industry companies. More importantly, I have gained extensive programming and system integration experience through closely working with a variety of sensing and automation technologies. These technologies include 3D imaging sensors (particularly laser scanning), radio frequency identification, global positioning system, vision sensors, autonomous robots, and many types of wave propagation related sensing devices. Such experience together with my background in civil engineering and computer science (signal processing, computer vision, pattern recognition, and data mining) empower me to develop innovative sensing systems for civil infrastructure systems.
