He works in the field of hydroinformatics for more than two decades, primarily in the areas of modelling different water systems (groundwater aquifers, catchments, urban water supply systems) and their coupling with optimization algorithms for purposes of decision support. His research has been particularly focused on using the Internet and mobile phone networks as platforms for new kinds of decision support systems in the water domain, aimed at broad stakeholder participation. He has participated in more than 10 large European collaborative research projects related to the field of ICT and water management, involving research partners as well as water and ICT industry partners. He has also participated in numerous hydroinformatics research, educational and capacity development projects with partners from Asia, Africa and Latin America.
