Dr. Xu develops and applies interdisciplinary system-based analytical tools to understand complex sustainability issues. This includes industrial ecology approaches (e.g., environmental input-output analysis, life cycle analysis, material flow analysis) and complex systems modeling methods (e.g., agent-based modeling, complex network analysis). Current focus of research includes "big data" mining and visualization, environmental implications of emerging bioenergy and clean vehicle technologies, and environmental impacts of international trade.
