Research

Connecting interface mechanisms to real environments.

Our environmental-biogeochemistry program examines how interactions among minerals, microorganisms and organic matter regulate carbon cycling and contaminant fate across croplands, permafrost, groundwater and water–sediment systems.

Mineral–carbon–contaminant interfaces

矿物—碳—污染物界面

How do minerals, microorganisms and organic matter jointly regulate carbon retention and electron transfer?

Soil carbon under climate and land-use change

气候与土地利用变化下的土壤碳

How do climate and land-use change alter soil-carbon accumulation and persistence-related properties?

We connect long-term field experiments, ecological-restoration chronosequences and global synthesis to study soil-carbon stocks and persistence-related indicators.

Scales & methods

From reactions in seconds to change across decades

Scale is not merely context; it is something to explain. We connect in-situ characterization, controlled experiments, long-term field observations and numerical models so short-lived mechanisms can inform environmental prediction.

Research cases

Testing mechanisms across environments and scales.

These cases show how the group connects interfacial chemistry, microbial processes, long-term observation and evidence synthesis.
