Curriculum Vitae:

Xiaolan Xu

Xiaolan Xu received the B.Eng. degree from Zhejiang University, Hangzhou, China in 2006, and the M.S. and Ph.D. degrees in electrical engineering from the University of Washington, Seattle, in 2008 and 2011, respectively. In 2012, she joined the Water and Carbon Cycles Group in Jet Propulsion Laboratory (JPL), California Institute of Technology, Pasadena as a postdoctoral research associate and became a scientist in Surface Hydrology group since 2014. Her research interests include theoretical modeling and numerical simulation in the random media and its application in microwave remote sensing of environment, especially in cryosphere.
