[General Information]

·         Ruiliang Pu received a B.Sc (Forestry) at Nanjing Forestry University (NFU), China, in 1982, an M.Sc (1985) from the same university studying remote sensing in forestry, earned a Ph.D. (Cartography & Geographic Information System, 2000), conducted at  Department of Environmental Science, Policy, and Management (ESPM), The University of California at Berkeley, from Institute of Remote Sensing Application (IRSA) of Chinese Academy of Sciences, and has been a lecturer in the Department of Forestry, NFU until 1990. He was a visiting scholar between 1990-1991 in the Earth Observations Laboratory, Institute for Space and Terrestrial Sciences, Ontario, Canada. Since 1993, he has been an Associate Professor with Department of Forestry, NFU. He was a visiting scholar in the Department of Geomatics Engineering, The University of Calgary, Canada, in 1994. In 1995, he moved to the United States.  He is presently employed as Assistant Researcher with the Department of ESPM, The University of California at Berkeley. He has had an excellent teaching experience in China and USA in both undergraduate and graduate courses and research experience in USA, Canada and China.  He has published more than 43 journal papers and books in English or Chinese.  He has been awarded the science and technology prizes three times by the Chinese government between 1986 and 1991 because of his excellent research achievements. His research interests focus on remote sensing in terrestrial ecosystem and biogeography, including evaluating productivity of forest land, ecosystem modeling, natural resources assessment & management, land use/cover change detection and environmental change detection, and on geo-spatial modeling with GIS & GPS and mathematical methods with an emphasis on the use of hyperspectral remote sensing data, GIS and GPS techniques.  He is also interested in teaching remote sensing in natural resources, biogeography, biology and environmental studies, and introduction to GIS at the graduate and undergraduate levels.
