Research

My research interests are on the use of remote sensing data and land surface models to study ecosystem dynamics, which includes:

1. the use of multi-sensor remotely sensed data for estimating ecosystem carbon and water fluxes
2. modeling ecosystem carbon fluxes at large scale using land surface models, and
3. investigating the influence of climatic variables on ecosystem functions.

My current research at 亚洲色图 State is focused on investigating the relationships between environmental controls and deciduous trees phenology to better understand climate change impacts on ecosystem functions. To answer such questions, I have started collecting leaf area index data and continuous soil temperature and moisture data at 亚洲色图 State's Hancock biological station (HBS). Also, students are measuring phenological development for several tree species in 亚洲色图 State campus as part of a partnership with USA National Phenology Network (NPN)
