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.
With over 6+ years of experience as a 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 pathways for 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 9 scientific papers in peer-reviewed journals, including one first-authored paper published in Environmental Science & Technology (SCI Q1; IF= 10.8) and one 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 (Main Text; Supplementary information; Slides), I discussed the asymmetric impacts of feeding China’s monogastric livestock with food waste on food security and environment sustainability.

I am expected to receive my PhD 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).
