Matilda van den Bosch is a Senior Researcher at the Barcelona Institute for Global Health, Spain, and an Adjunct Professor at the University of British Columbia, Canada, with a shared appointment between the Faculty of Medicine and the Faculty of Forestry. She has a background in medicine and her interdisciplinary research line lies in the interface of human health and the health of natural environments with the goal of contributing to evidence and policies that promote healthy environments for both humans and ecosystems. Most of her studies have focused on the health benefits of contact and exposure to urban natural environments, especially for children. Findings from her research suggest that exposure to green and blue spaces promotes childhood health and development and reduces the risk of neurobehavioural problems. She has published more than 50 peer-reviewed scientific articles and is the primary editor of the Oxford Textbook of Nature and Public Health (2018). She is also leading several international research projects related to climate change, childhood health, and green space mitigation. In addition, she advises various international organizations, including the World Health Organization, the UN Environmental Programme, and the US Environmental Protection Agency.
