Dr Chang’s overarching research goal is to improve the knowledge of interdependence between human and environment during the rapid urbanization process via engineering, analytical and management approaches. He is leading a research team that has two major research focuses. The built environment-human nexus subgroup has wide interests in the urban air quality and built environment related fields, such as indoor/outdoor air pollutant dynamics, pollutant transport/mixing phenomena in HVAC system, semivolatile organic compounds, urban/indoor air microbiome, source/exposure characterization. The resources reclamation and impact assessment subgroup has been working in urban waste management, waste to materials/energy, and life cycle assessment fields. The research efforts include resource reclamation technologies, urban waste re-utilization/recycling, environmental trace organics, and life cycle and impact assessment.
