Professor Graham has been a Visiting Professor at Harbin Institute of Technology, China, and Nanyang Technological University, Singapore, and is an Honorary Professor at the Hong Kong Polytechnic University. During the period 2000-2002 Professor Graham was Chair Professor and Director of the Research Centre for Urban Environmental Technology and Management, School of Civil and Structural Engineering, Hong Kong Polytechnic University (on secondment from Imperial College London).

Professor Graham’s technical and research interests are principally related to the design, operation, performance and development of a wide range of unit processes in water and wastewater treatment, and in the management of water supply systems. His research studies over 30 years have involved laboratory and pilot-scale experiment evaluations as well as process modelling and simulation. In recent years Professor Graham has focused his research studies on oxidation, coagulation and filtration processes, and in aspects of water supply network analysis. His current portfolio of projects range from the evaluation of electro-coagulation technology and novel polymer coagulants, advanced oxidation methods (eg. combinations of ozone and ultrasound, catalytic ozonation, ferrate with/without photocatalysis), to the development of computer-based process models (eg. granular filtration) and advanced water supply monitoring via wireless sensor networks.

Prof. Faulstich’s (b. 1957) research focuses on strategies and concepts for a sustainable industrial society. His Chair analyzes technical value chains to identify ways to improve resource efficiency and develops processes to create and use renewable resources and energy sources (hydrogen, methane and methanol).
After studying mechanical engineering and process engineering in Dusseldorf and Aachen, Martin Faulstich completed his doctorate in environmental engineering at TU Berlin in 1992. He became professor of waste management at Technische Universität München in 1994. Since 2003, he has held the Chair of Resource and Energy Technology. Prof. Faulstich lectures and researches in the field of resource strategies as well as renewable energy systems.

Prof. Faulstich is also founding director of the Straubing Center of Science which is an intersectoral and multidisciplinary research facility of biogenic resources of different scientific disciplines. The center is based on five Bavarian universities and is working on mutual research projects. These projects investigate the material use as well as the energy use of biogenic resources. Faulstich is also scientific director of the ATZ Entwicklungszentrum a science and engineering-oriented development center in Sulzbach-Rosenberg. The ATZ Entwicklungszentrum develops concepts and processes which directly relate to the economy in order to allocate and make an efficient use of energy, raw materials and materials.

Besides Prof. Faulstich is chairman of the German Advisory Council (SRU) on the Environment which is the first academic advisory body in the history of German environmental policy-making. It consists of seven university professors from a range of different environment-related disciplines and is politically independent in advising the German government.

Prof. Faulstich is a member of several boards of trustees and advisory boards (including the ifo Institute for Economic Research, the Potsdam Institute for Climate Impact Research, the Institute of the Regions of Europe in Salzburg and the International Sakharov Environmental University Minsk).

Prof Joseph Hun-Wei LEE took office as Vice-President for Research and Graduate Studies at Hong Kong University of Science and Technology on 1 November 2010.

Prof Lee grew up in Hong Kong and obtained his BSc, MSc and PhD degrees in Civil Engineering all from the Massachusetts Institute of Technology (1969-1977). He joined the University of Hong Kong (HKU) in 1980, where he rose to Redmond Chair Professor of Civil Engineering in 1995. At HKU, he was Dean of Engineering from 2000 to 2003, and Pro-Vice-Chancellor and Vice-President from 2004-2010.

Professor Lee's research revolves around the use of hydraulics to solve environmental problems, in particular the prediction and control of water quality. He is Editor of the Journal of Hydro-environment Research and Vice-President of the International Association for Hydro-environment Engineering and Research – IAHR (2007-2011), and has served as expert consultant on numerous hydro-environmental projects. He serves on the Advisory Council on the Environment and the Construction Industry Council of the Hong Kong SAR Government, as well as advisory bodies in Scotland, Germany and Singapore. He is Honorary Professor of Nankai University, and a member of the Shanghai Committee of the Chinese People's Political Consultative Conference (CPPCC).

Professor Lee is the first Asia based academic to receive the Hunter Rouse Hydraulic Engineering Award from the American Society of Civil Engineers (2009). He is a Fellow of the Royal Academy of Engineering, United Kingdom, and Fellow of the Hong Kong Academy of Engineering Sciences. He and his research team were bestowed a State Scientific and Technological Progress Award (Second Class) 2010 by the Chinese State Council.

Dr. Joseph Cotruvo is president of Joseph Cotruvo and Associates, LLC, Water,
Environment and Public Health Consultants. His doctorate is in Physical Organic Chemistry from Ohio State University. He is a longtime member of the World Health Organization’s Guidelines for Drinking-water Quality Committee, and serves on numerous expert advisory groups on drinking water quality, desalination, and for several water reuse projects.
