Dr. Qian Zhang is an Assistant Professor in the Robert M. Buchan Department of Mining at Queen's University in Canada. He leads a research group fostering a roadmap of green mining in Canada and internationally through strategic management of sustainability and resilience challenges in the mining value chain.

Zhang's main research interests are climate change mitigation, mineral resource management, and urban sustainability. His research focuses on greenhouse gas (GHG) accounting, carbon footprint analysis, and policy-oriented modelling of other environmental pressures (natural resource depletion, water scarcity, air pollution, solid waste, etc.) on the built environment using analytical methods, such as input-output analysis, material flow analysis, and life-cycle assessment.

Previously, he worked as a postdoctoral fellow at the University of Victoria and the University of Tokyo. He has consulting experience in the area of climate and energy for the World Resources Institute (WRI).

Zhang earned a Ph.D. in Urban Engineering from the University of Tokyo, where he was a recipient of the Japanese Government (MEXT) scholarship. He also holds an MSc in Environmental Science, a BSc in Environmental Science, and a Minor in Economics, all from Peking University.
