Joost van Summeren is a scientific researcher on the Water Infrastructure team. His research focuses on an improved insight into the quality and quantity of drinking water in distribution networks and real-time monitoring by means of sensor networks. His work includes the development and application of new measurement methods and data analysis techniques and numerical water quality modelling. He also works on practical research with testing grounds, pilot plants and living labs. For example, he contributed to the development of a drinking water network on a laboratory scale for research in smarter distribution networks. Joost used big data techniques to research the link between brown water reports and temperature, pipeline properties and demographic factors. An example of applying new measuring methods is identifying substance concentrations in drinking water by interpreting sensor signals by means of an artificial neural network algorithm. With a background in theoretical geophysics, Joost has knowledge of liquid dynamic processes and numerical modelling techniques. At KWR, he developed his expertise in projects in collaboration with the sector and by participating in international conferences. He is a guest editor for Water, special issue on “Water Quality in Drinking Water Distribution Systems” http://www.mdpi.com/journal/water/special_issues/Drinking_Water_Distribution.
