Dr. Liu has developed a 3-step GPR field analysis protocol for detecting shallow delamination in continuously reinforced concrete pavements. Her research has led to more than 60 peer-reviewed publications.

Hai Huang, Ph.D., P.E.
Assistant Professor, Civil Engineering, Penn State University Altoona

Dr. Huang obtained his Ph.D. in Railroad Engineering from the University of Illinois at Urbana-Champaign. His expertise includes track dynamics and track substructure Discrete Element Modeling (DEM). Dr. Huang has more than 20 publications on track dynamics and DEM modeling. He currently serves as the Principal Investigator of a dynamic track model development project funded by the Federal Railroad Administration. He is also a registered Professional Engineer in the state of Ohio.

Tian Xia, Ph.D.
Associate Professor, Electrical and Computer Engineering, University of Vermont

Dr. Xia has conducted extensive research on radar signal processing, circuit design and test, and integrated circuit signal integrity analysis and modeling. His recent research focuses on developing high-speed and high-performance GPR for highway and bridge inspections, and non-invasive human vital sign detection UWB radar for disaster rescue operations. He holds five U.S. patents with two others pending.

Kaiguang Zhao, Ph.D.
Postdoctoral Researcher, Joint Global Ghange Research Institute

Dr. Zhao obtained his Ph.D. in environmental remote sensing from Texas A&M University. His dissertation work developed a real-time on-the-flight airborne profiling laser system for regional resources inventory. He also proposed many efficient algorithms for feature extraction and pattern recognition to process image and laser point clouds data. His recent research in laser mapping includes laser systems from ground, airborne, and spaceborne platforms.
