We study the interactions between the terrestrial biosphere, the atmosphere and anthropogenic drivers.  Our research methodology consists of field observations (eddy covariance,  optical isotope instruments,  and high-precision greenhouse gas analyzers), mathematical models (land surface models, large-eddy simulation, WRF, and earth system models), and environmental remote sensing (satellites and drones).   

Ongoing projects include (1)  subgrid parameterization in earth system models, (2)  isotope-enabled large-eddy simulation, (3) modeling and observational study on biophysical effects of land use (deforestation, urbanization, irrigation) on local climate, (4) urban microclimate mitigation,  (5)  experimental study of  carbon and water isotopes in terrestrial and urban ecosystems, and (6) eutrophication effects on lake-air fluxes of greenhouse gases.
