I received the B. Sc. in forestry in 2001 and the M. Sc. degree in forest management in 2004 both from Beijing Forestry University. In 2007, I received the Ph. D. degree in quantitative remote sensing at the Institute of Remote Sensing Applications of the Chinese Academy of Sciences, Beijing, China. I have been working in the Forestry College of Beijing Forestry University since 2007. Now, I serves as an associate professor in the group of Forest Management. My research interests include 3-D modeling of reflectance and thermal emission of land surfaces (vegetation in particular) and remote sensing applications in agriculture and forest environment.
