Leon Hermans works as an assistant professor in Policy Analysis at Delft University of Technology. He teaches courses on actor and strategy models and policy analysis for multi-actor systems at both graduate and undergraduate level. His current research interests are the use of monitoring and evaluation to support learning for adaptive management in multi-actor environments.

Leon now leads a four year NWO project on transformations in groundwater management in per-urban areas in India and Bangladesh and is a co-leader of research projects on strategic delta planning in Vietnam, Bangladesh and the Netherlands, and the governance of nature-based flood defences in the Netherlands. Other recent work includes commissioned research for the Delta Programme in the Netherlands for the design of an evaluation framework to support adaptive delta management.

Earlier, Leon worked for the Food and Agriculture Organization of the United Nations (FAO), based at its headquarters in Italy, from 2003 to 2006. Here he worked at the Water Resources Management and Development Service, focusing on water valuation and integrated approaches to water resources management. Leon obtained his degrees from TU Delft. He holds a PhD degree in policy analysis, with a dissertation on the use of actor analysis methods in water resources management.
