My postdoctoral research at the University of Macau focuses broadly on the coupling of water and biogeochemical cycling, with interests spanning agricultural environments, isotope geochemistry, the Earth's critical zone, the Anthropocene environment, and global change. My work adopts a cross-scale perspective to explore how natural processes and human activities jointly shape the evolution of aquatic environments, with particular attention to the cumulative and lagged effects of these interactions across both temporal and spatial dimensions. Methodologically, I integrate isotope geochemistry, machine learning, and high-frequency monitoring to examine the mechanisms and patterns of material cycling in water systems, from catchment to regional and global scales. My publications encompass groundwater quality, agricultural non-point source pollution, greenhouse gas emissions, and spatiotemporal variability in water chemistry, reflecting a systematic interest in the coupled cycling of water, carbon, and nitrogen within the Earth's critical zone. Looking ahead, I will continue to pursue questions at the intersection of Anthropocene environmental change and global change, focusing on the responses and feedbacks of water–biogeochemical cycling under the dual drivers of natural processes and human activities. Through integrative research, I aim to provide a scientific foundation for sustainable water resource management and environmental resilience.
