Kimo van Dijk is doing his PhD research on nutrient management and phosphorus (P) security at Wageningen University supervised by prof. Oene Oenema. Kimo analyses the present P flows in Europe (EU-27) at the country level, develops dynamic nutrient flow models, and simulates potential future P use by scenario analyses. Additionally, he supervises master students studying the P flows and future nutrient management options at the local level in cities (Rotterdam and Wageningen). In the past he did scientific studies for the Dutch government about the options for sustainable P use in the Dutch, West-European and European society. Besides his scientific work he also actively participates in the Dutch Nutrient Platform and the European Sustainable Phosphorus Platform, and other networks. His academic background encompasses Biology (BSc.) and Biological Sciences (MSc.) both at the University of Amsterdam, including the study of ecology, evolution, biodiversity, adaptation, biological pest control, plant-animal-human interactions. His thesis was about the global dietary protein balance and options for enhancement under supervision of prof. Louise O. Fresco.
