Research Interest

Terrestrial ecosystem modeling, remote sensing of ecosystem dynamics, GIS application in natural resources, Land use and land cover change, Fire ecology

Research Experience

•Forest conservation and reforestation in Mississippi Alluvial Valley (2018 - present): Reconstruct century-long (1850), high-resolution (30 m) land use and land cover data in the Mississippi Alluvial Valley and apply land ecosystem model to evaluate GHG emissions and water quality improvement during the reforestation process.

•Terrestrial ecosystem model development and improvement (2009 – present): Improve model representations of fire, vegetation dynamics, soil carbon decomposition, agriculture, photosynthesis, evapotranspiration, and soil moisture and soil temperature on the platform of the Dynamic Land Ecosystem Model (DLEM).

•Model inter-comparison projection and data analysis (2010 – 2018): The major contributor of the DLEM model simulations for Multi-Scale Synthesis and Terrestrial Model Intercomparison Project (MstMIP, 2010-2012), Inter-Sector Impact Model Intercomparison Project (ISIMIP, 2015 - present), and Dynamic Global Vegetation Model project (GCP-Trendy, 2016 - present).

•Remotely-sensed terrestrial ecosystem dynamics (2010 - present): Explore the dynamics of ecosystem photosynthesis and greenness in response to environmental changes and climate extremes by using SIF, EVI, and NDVI.

•Fire impact on ecosystems (2010 - present): Investigate the impact of prescribed burning on forest productivity. Examine regional and global fire regimes and their impacts on the land ecosystems by using the remote sensing and land ecosystem modeling.

•Water, carbon, and nitrogen exports from Mississippi River (2013 - 2016): Study the water, carbon, and nitrogen exports from Mississippi River under the impacts of climate change, land use change and management, and CO2 concentration increase.
