Since April 1st, 2023 I am professor of philosophical ethics at the Ethics Institute / Department of Philosophy and Religious Studies, Utrecht University. My main interest is in practical ethics, notably public health ethics, and in the relationships between moral philosophy, normative theory and practical ethical decision making. My major research theme in the past years was vaccination ethics: Together with Roland Pierik I completed a monograph Inducing Immunity? The Justification of Collective Immunization in Times of Vaccine Hesitancy. The book will be published late 2023 by MIT Press, in the Basic Bioethics book series, open access! Apart from vaccination policies I'm currently involved as advisor at Zorginstituut Nederland, as member of the committee that advises on contents of the (mandatory) basic health insurance package.A general theme in the last years and presumably upcoming years is to gain a better understanding of the normative character of the value of (health) solidarity, and its links with sustainability. This theoretical issue is relevant to policy questions in relation to vaccination, infectious disease control, local and global health inequalities, and access to health care. Together with Angus Dawson the International Association of Bioethics network on Public Health Ethics. We also started the journal Public Health Ethics, published by OUP, of which I was Editor in Chief until 2022. From 2013 to 2023 I was professor of philosophy at Wageningen University, leading the Philosophy group. This is a vibrant group of philosophers working on animal and environmental ethics, philosophy of technology and public health. In my last year I also lead the 4TU Centre for Ethics and Technology, of which Wageningen is one of the 4 partners.
