University of California, Santa Barbara

Yuwei Qin is a third-year PhD student in the Bren School of Environmental Science & Management at the University of California, Santa Barbara, where she earned her master’s degree in Environmental Science and Management. She also has a B.S. in Environmental Policy and Management with an emphasis on Environmental Economics at the Ohio State University. Yuwei studies Life Cycle Assessment (LCA) with an emphasis in assessing uncertainty of LCA results and improving reliability of LCA applications. She is currently working on an environmental and health impact-predicting tool for new chemicals, called Chemical Life Cycle Collaborate (CLiCC), and mainly focusing on the uncertainty and sensitivity analysis of the results. She previous research involves the uncertainty quantification of Ecoinvent data (the world largest LCA database) and the determination of probability distribution of inventory data.


        Understanding marginal production is an important step toward modeling the life cycle environmental consequences of changes in a production system. In this study, we demonstrate how marginal production... [ view full abstract ]
