Research and Background

My interdisciplinary research focuses on developing computational models, automated algorithms and hardware systems using remote sensing technologies and spatial analysis techniques as they are applied in the fields of transportation asset management, geometry design and roadway safety, pavement preservation and maintenance, and many other critical transportation applications. I make continuous effort towards establishing a comprehensive, spatially-enabled transportation infrastructure and asset data platform through employing the emerging sensing technologies (such as light detection and ranging (LiDAR), computer vision, continuous scanning laser), and developing computational data analysis techniques (such as image processing algorithm, geographic information system (GIS) spatial analysis).
