Welcome to my personal website!
I am a PhD candidate from Environmental Economics and Natural Resources Group (ENR) group in Wageningen University & Research. I am supervised by Associate Prof. Dr. Xueqin Zhu, Associate Prof. Dr. Hans-Peter Weikard, Prof. Dr. Oene Oenema from Wageningen University & Research, as well as Prof. Dr. Yong Hou from China Agricultural university. I will be conducting research as a visiting PhD student at University of California, Davis under the supervision of Assistant Professor Dr. Luis M. Peña-Lévano from October 2024 to January 2025.
I am scheduled to submit my PhD thesis in June 2025, with my defense anticipated in September 2025. Currently, I am seeking academic opportunities for the 2024-2025 academic year. I am available for interviews at both the European Job Market (EJME) and the Allied Social Science Associations (ASSA).
With over 6+ years of experience as a Quantitative researcher and economist, I specialise in integrated environmental-economic modelling and environmental impact assessment. My expertise lies in applying quantitative modelling approaches to explore mitigation options towards sustainable food systems. My PhD dissertation focuses on assessing the impacts of food system transformation pathways—such as supply-side and demand-side measures, and environmental policies—at the regional, national, and global levels. I employ an integrated environmental-economic modelling approach based on a computable general equilibrium framework that is able to represent regional consumption, production, environmental variables, and international trade with other regions.
I have published 10 scientific papers in peer-reviewed journals, including two first-authored papers, one published in Environmental Science & Technology (SCI Q1; IF= 10.8) and the other in Sustainable Production and Consumption (SCI & SSCI Q1, IF=10.9), along with a co-authored paper published in Nature Food (SCI Q1; IF=23.6). For a full list of my publications, please check on Google Scholar.
In my Job Market Paper [Full Paper] [Slides], I highlighted that rebound effects may undermine benefits of upcycling low-opportunity-cost feed as animal feed in China, and a modest mitigation target could address these rebound effects in China while safeguarding global food security.
