My research focuses on the perception and assessment of environmental and health risks. Since 2006, I have been collaborating on several research projects to determine the integrated exposure of environmental pollutants in people's bodies with human biomonitoring. Within these interdisciplinary projects I pay attention to the social impact and meaning of human biomonitoring for participants, (local) stakeholders, scientists and policy makers. This is done by setting up local participatory procedures and inter- and transdisciplinary dialogue. Topics include risk communication, perception, ethics and policy translation. Throughout this 'boundary work' I am particulary interested in mechanisms of social vulnerability and exclusion, health inequalities and environmental justice.
