Hello! My name is Fenghui (pronounced “fown-hui”).

My work focuses on understanding water–carbon dynamics in natural and agricultural ecosystems as the environment changes using interdisciplinary approaches. I combine field observations, experiments, and process-based modeling with data-driven approaches in a Model–Experiment (ModEx) integration framework to reduce uncertainties in predicting how ecosystems respond. Through this work, I also engage in teaching and mentoring, helping students and collaborators develop skills in ecosystem science and modeling.

Specifically, my research interests include:

  • Observations and experiments: Quantifying how environmental drivers[1, 2], plant traits[3, 4, 5], and soil microbial processes[6, 7] regulate carbon cycling and water-use efficiency, particularly in sensitive systems such as permafrost regions[8, 9, 10], wetlands[11], and forests and croplands undergoing land-use change[12, 13, 14].

  • Process-based modeling: Improving process-based models by integrating field observations, manipulative experiments, and data-driven approaches to better represent water–soil–plant interactions under changing environmental conditions[15, 16, 17, 18].

  • AI-driven modeling: Developing Artificial Intelligence (AI)-enabled predictive frameworks to inform sustainable land management and evaluate trade-offs among land productivity, resource use, and environmental outcomes[19, 20, 21, 22, 23].
