I have co-supervised several undergraduate/graduate students:

• Liu Baojian, undergraduate/graduate student at PKU. His research focused on GNSS remote sensing and hydrological remote sensing. He has worked at Beijing Forestry University since 2022.

• Fang Weizhen, graduate student at PKU. His research focused on hydrological remote sensing.

• Ji Rui, undergraduate/graduate student at PKU. His research focused on hydrological remote sensing.

• Guo Zhizhou, undergraduate/graduate student at PKU. His research focused on GNSS remote sensing.

• Wan Xianci, graduate student at PKU. Her research focused on GNSS remote sensing.

• Zhang Jie, visiting student at PKU. Her research focused on GNSS remote sensing.

I participate in several graduate courses, i.e., Global Change and Remote Sensing Water Cycle, Satellite Navigation Principles and Applications, and Water Resources-Water Environments-Water Disasters Information System.

My research interests relate to GNSS remote sensing. I am currently focusing on GNSS Reflectometry (GNSS-R) and its application in land hydrology. It mainly involves GNSS-R mechanisms and methods for deriving key hydrological components, e.g., soil moisture, snow/ice, and surface water. I am also interested in other science and technology issues on GNSS remote sensing interacting with the atmosphere, ocean, and land.
