I am a Postdoctoral Researcher jointed between Peking University (PKU) and International Institute for Applied Systems Analysis (IIASA), working with Prof. Lin Zhang, Dr. Petr Havlik and Dr. Wilfried Winiwarter.

I conduct interdisciplinary research on the technological, policy, and social opportunities for a sustainable food future.  Agriculture is central to major environmental and health challenges such as reactive nitrogen losses and associated air and water pollution, greenhouse gas emissions, land and water use, dietary health, etc.

I am fascinated by the fact that improvements in the food system can help achieve multiple sustainable development goals, i.e. improving planetary health while providing nutrition and equitable food to everyone. I enjoy working with experts across disciplines for research that can inform environmental policymaking. I use both quantitative (reactive nitrogen emission and air quality modeling, integrated assessment, cost-benefit analysis and public health analysis) and qualitative research methods (interviews, surveys and scenario analysis).

I received my Ph.D. in environmental studies and public affairs from the Princeton School of International and Public Affairs at Princeton University, advised by Prof. Denise L. Mauzerall and Dr. Tim Searchinger. My PhD dissertation explored the potential of improving agricultural production and consumption practices in China for clean air, public health, resource saving and climate change mitigation. I received a B.S. in atmospheric and oceanic sciences from the School of Physics at Peking University. I have worked as a volunteer for the Nature Conservancy's Beijing Office on climate change adaptation and as a short-term consultant for the World Bank on China’s nitrogen use.
