PROFILE

 

Xiaoyi Liu is currently a Ph.D student (advisor: Professor Peter Kitanidis) in Environmental Fluid Mechanics and Hydrology at Stanford University. He Received a B.S. degree in Hydrological and Geological Engineering (currently the Department of Hydrosiences) from Nanjing University (南京大学), China in 2002. After gruaduation he went to Tibet and served as a volunteer teacher in Lhasa Beijing High School (拉萨北京中学) until 2003, after which he returned to Nanjing University for graduate study. Then, he continued his graduate study at the University of Iowa, where he acquired his M.S. degree in Geoscience on hydraulic tomography in 2006. Before coming to Stanford University in 2007, he was also a graduate student in the Department of Statistical and Actuarial Science in the University of Iowa.
