Biographical details

John Little recently joined the School of Civil Engineering at the University of Sydney as Professor of Water Resources Engineering. He received a BS in Chemical Engineering from the University of Cape Town and an MS and PhD in Environmental Engineering from the University of California, Berkeley. After completing a Postdoctoral Fellowship at Lawrence Berkeley National Laboratory, he spent 20 years on the faculty in the Charles E. Via, Jr. Department of Civil and Environmental Engineering at Virginia Tech in Blacksburg, Virginia, ending his tenure there as Charles E. Via, Jr. Professor. His primary research interests are cross-media mass transfer and process dynamics in a wide array of environmental systems, with emerging interests in sustainable systems research. Dr. Little received a National Science Foundation (NSF) Career Award in 1996, was elected to the International Society of Indoor Air Quality and Climate (ISIAQ) Academy of Fellows in 2008, received the Association of Environmental Engineering and Science Professors (AEESP)/CH2M Hill Outstanding Doctoral Dissertation Award in 2011, and an AEESP Distinguished Service Award in 2013. He is currently Chair of the International Water Association (IWA) Specialist Group on Lake and Reservoir Management as well as Chair of the ISIAQ Scientific and Technical Committee: Sources, Monitoring and Evaluation: Chemicals. While at Virginia Tech, he served as Director of a $3M NSF Integrative Graduate Education and Research Traineeship (IGERT) Program called EIGER - Exploring Interfaces through Graduate Education and Research. During two year-long sabbaticals, Dr. Little has been a visiting professor in the Department of Surface Waters, Swiss Federal Institute for Aquatic Science and Technology (Eawag), Switzerland, the Department of Building Science, Tsinghua University, China, the Department of Environmental Engineering, National Cheng Kung University, Taiwan, and the Instituto del Agua, University of Granada, Spain.
