报告人简介：

Christoph Helbig is Professor of Ecological Resource Technology at the University of Bayreuth, Germany. His research focuses on sustainable material cycles, criticality assessment of raw materials, and life cycle analysis. He develops quantitative methods for modelling global flows of technology metals and assessing the supply risks of critical raw materials. He is the Principal Investigator of the ERC Starting Grant project SEMPATHY on composition-aware material cycle modelling. He received the 2023 Laudise Medal from the International Society for Industrial Ecology and serves as Co-Chair of the ISIE Section on Socioeconomic Metabolism.
