Mechanistic modelling for ecotoxicology and ecology

DEBtox Researc

This page contains an overview of the most important projects that I am, or have been, a partner in. This list starts at 2004, and I only include projects that have funded my salary (directly or, while I was employed at the VU university, through funding PhD positions) and official advisory positions. Since January 2015, I run projects through my private company DEBtox Research. For the confidential projects, I am usually/probably not allowed to mention the client on my website. However, most of these projects will eventually lead to publications, that will appear in the publication lists at
