James O. Leckie

Prof. Leckie has been on the Stanford Environmental Engineering faculty since 1970 and is an environmental chemist interested in the application of chemical principles to the study of pollutants behavior in natural aquatic systems and in engineered processes. His research contributions have been extensive in the areas of adsorption chemistry, human exposure analysis, and membrane science. In 2005, he became a member of the National Academy of Engineering, and received the American Society of Civil Engineering Rudolf Hering Medal in 1981. Presently, he is co-Director of the Singapore-Stanford Partnership program in Environmental Engineering & Science, and Director of the Center for Sustainable Development & Global Competitiveness at Stanford University. He is also Appointed Chair Professor in the Department of Environmental Science and Engineering at Tsinghua University. Prof. Leckie holds a B.S. degree in Civil Engineering from San José State University (1964), and M.S. (1965) and Ph.D. (1970) degrees in Environmental Sciences from Harvard University.
