I am an associate professor in Hydrology at the University of Twente, the Netherlands. I hold an MSc degree in Hydrology and Quantitative Water Management from Wageningen University and a PhD degree in Hydrology and Climatology from the University of Twente. My research interests and activities focus on catchment hydrology in general and modelling of hydrological systems, assessment of environmental change impacts on hydrology and water resources and uncertainty analysis in particular. These research themes are reflected in my past and on-going research projects, international collaboration and over 125 scientific publications. I was and am involved in projects and studies in many countries in the world including Indonesia, China, Vietnam, Pakistan, Iran, Rwanda, Kenya, Germany, France and Belgium. I teach in the area of hydrology, hydrological modelling and water management and supervise PhD students, MSc theses and BSc theses. I have contributed to international training courses in Indonesia and China and provided guest lectures and keynotes in several countries (e.g. China, Pakistan, India, Thailand, Vietnam, Poland).
