These experiences led her to focus increasingly on activism, both within and beyond the healthcare sector. Juliette works towards a new narrative on health, engaging with themes such as the social and political determinants of health, the right to self-determination over land and bodies, the decolonisation of medicine, and the building of collective alternatives rooted in care, solidarity, equality, and wellbeing.Dr. Evelyn Brakema is a GP and post-doctoral researcher on sustainable healthcare at the Leiden University Medical Centre (LUMC), and the co-founder and chair of the Dutch Green Health Alliance (Groene Zorg Alliantie) in the Netherlands, which she helped establish as a grassroots network to mobilise health professionals towards action for planetary health.
