Z. (Bob) Su is Professor of Spatial Hydrology and Water Resources Management and chairman of the Department of Water Resources in the Faculty of Geo-information Science and Earth Observation (ITC) of the University of Twente, the Netherlands. Bob Su earned a Ph.D. degree in Civil Engineering from Ruhr University Bochum in Germany, a postgraduate diploma and a M.Sc. degree with Distinction in hydrological engineering from the UNESCO-IHE Institute for Water Education in Delft, the Netherlands and a B.Sc. degree in Hydraulic Engineering from Taiyuan University of Technology in China.

From 1994 to 1996, he worked as a post-doc researcher at the Laboratory of Hydrology and Water Management in the Faculty of Agriculture and Applied Biological Sciences of University of Ghent in Belgium. He was a senior scientist in remote sensing and hydroclimatology at Wageningen University and Research Centre, Alterra Green World Research before he joined ITC in October 2004. He was appointed as Guest Professor of the School of Water Resources and Environment, China University of Geosciences in Beijing in 2001 and as Guest Professor of the Institute for Tibetan Plateau Research, Chinese Academy of Sciences in 2005. Bob Su’s current research and teaching focus on remote sensing and numerical modeling of land surface processes and interactions with the atmosphere, Earth Observation of water cycle and applications in climate and ecosystem and water resources studies, and monitoring of food security and water-related disasters. He has acted as project manager, principle investigator and co-investigator of various projects supported by the Dutch Remote Sensing Board, the Dutch Ministry of Agriculture, Nature and Fishery, the Royal Dutch Academy of Sciences (KNAW), the Netherlands Science Organization (NWO), the European Commission framework programme and the European Space Agency (ESA). Bob Su served as a member of the International Scientific Steering Committee of the HYdrological cycle in the Mediterranean EXperiment (ISSC HyMeX). He was Netherlands representative to the intergovernmental ad hoc Group on Earth Observation (GEO) charged to develop a 10 year implementation plan for integrated global Earth Observation. He is a member of European Geosciences Union (EGU) and IAHS and serves as the chair of sub-division of Remote Sensing and Data Assimilation of EGU and is a member of the Hydrology Section Technical Committee of AGU. Bob Su is also currently member of the Earth Science Advisory Committee (ESAC) of the European Space Agency and member of the Science Committee of the Third Pole Environment programme (SC TPE). Bob Su has published actively in refereed journals and conference proceedings and serves as reviewers and editors for several international journals.

Activities in education

Bob Su lectures in Water resources research from space, Advanced remote sensing and GIS application in water resources, Remote sensing in water management and new remote sensing techniques. He supervises MSc and PhD students (4 graduated, 18 ongoing) in quantitative remote sensing and numerical modelling of land surface processes, land atmosphere interactions, earth observation of water cycle and applications in climate and ecosystem studies, as well as in monitoring of food security and water-related disasters.
