Dr. Zhang Shu is Assistant Professor of the Institute of Energy, Environment and Economy at Tsinghua University. His research focuses on integration and interactions across energy, land, water, and air quality systems, with particular emphasis on cross-sector synergies. He develops and applies the energy-environment-economy model China TIMES to explore pathways that integrate energy, transport, buildings, and industry sectors, while accounting for sharedinfrastructures such as power grid, storage and CO₂ transport network. A central strand of his research is quantifying uncertainty in decarbonization pathways using the probabilistic framework, which enables robust policy recommendations. With publications in Nature Sustainability, Nature Communications, and Engineering, He has contributed new insights on the costs, potentials, and enabling policies of integrated low-carbon transitions, and provides evidence-based insights to support strategic policymaking.
