Biography

I am a professor and senior scientist in the Geospatial Sciences Center of Excellence with a tenure home in the Geography department. Prior to joining SDSU in 2013, I was a Research Assistant Professor with the Institute of Hydrobiology, Chinese Academy of Sciences (CAS), China (1984-1988); a Research Associate Professor with the Institute of Geodesy and Geophysics, CAS, China (1988-1995); a Research Associate and Research Assistant Professor with the Department of Geography, Boston University, Boston, MA, USA (1999 to 2005). As a Senior Research Scientist in the Earth Resources Technology (2005-2012) and a visiting Associate Research Scientist in the University of Maryland (2012-2013), I worked at the National Oceanic and Atmospheric Administration (NOAA), National Environmental Satellite, Data, and Information Service, Center for Satellite Applications and Research (STAR), Camp Spring, MD, USA. Moreover, I am a journal editor of
