2011-2012 Postdoc, Research Scientist
Carried out NASA postdoc program focusing on changes in the terrestrial water cycle under a changing climate and the role of vegetation plays in it.
2008-2010 Research Assistant
Establish a 24-years long hydrological variable dataset including fractional cover (fc), precipitation, soil moisture, ET datasets in Hai basin, to assist evaluation on ecological and environmental effects of water conservancy in North China.
2005-2008 PhD candidate
Developed an algorithm for estimating regional evapotranspiration from MODIS data and meteorological data, which algorithm is an integration of Penman-Monteith equation and SEBS model. Relevant ground validation was done to localize model parameters based on flux towers.
