I am professor of Water Resources Management with a focus on water, environment and development research and consultation.  My research concentrates on sustainable development and water resources management in developing and emerging economies, particularly in Asia. In my particular interest are global water resources and their interrelations to sectors such as agriculture and energy, and in relation to drivers such as climate change, urbanization, poverty, environment and economic development. 

I am active in several international organizations including UNESCO, WMO, IWRA (Vice President 2007-2009), IWA, IIASA and UNU/WIDER. I was a Vice Dean of Reseach and Innovation of Aalto School of Engineering in 2013-2018, Counsellor at the Supreme Administrational Court of Finland in 2006-2015, and am Distinguished Adjunct Professor at Asian Institute of Technology, Thailand.
