  • Profile

    Tjerk Jan Schuitmaker-Warnaar works as education developer at the University of Amsterdam’s Institute for Interdisciplinary Studies. He recently received a Comenius grand for scaling up the Change Making educational program. As assistant professor and PI within APH he worked on sustainability transitions in health care, focusing on financial feasibility, environmental impact, and sustainable health.

    He co-develops transdisciplinary educational and research programs around the Healthy Future theme and has led or contributed to numerous initiatives, including NATURELAB (nature-based therapies in health care), Welzijn op Recept (social prescribing), HiNoord (shifting from care for disease to care for health), Doing eHealth Right (inclusive digital health), and SUPREME NUDGE (promoting healthy lifestyles through supermarkets). He has also worked with national bodies such as ZonMw and ZiNL on methodology development, patient engagement, and integrating environmental impacts into health technology assessment. Trained as a biomedical scientist with a specialisation in neurbiology, he earned his PhD in political science on persistent problems in Dutch health care, as part of the KSI-network on sustainability transitions.

    As a lecturer, he teaches courses on science, technology, and society, and has supervised more than 200 student internships and theses.

    • As TLC Research Fellow he reseaches educational tools to enhance Self Regulated System Learning.
    • With the Change Making Community of Action, he builds sustainable partships between societal partners, researchers and students through education.
    • With Welzijn op Recept, he worked on the implementation of a cross-domain care for health concept.
    • Within Doing eHealth Right, he contributed to inclusive eHealth development.
    • As project leader of NATURELAB, a European consortium that researches the benefits of nature-based therapies, he integrated NBTs into existing healthcare structures.
    • Within Leren en Verbeteren in de zorg, he collaborated with ZonMW on methodology development and research for continuous learning and improvement.
    • He monitored and evaluated HiNoord!, which worked on accelerating the transition to care for health, as opposed to disease care.
    • He worked with ZiNL on Green Metrics, incorporating environmental effects in HTA.
    • He was work package leader within the PARADIGM consortium, focused on developing tools for monitoring and evaluating the value and impact of patient involvement.
    • Within Het Bewustzijnsproject, he supported the implementation of high-quality cost-conscious care projects.
    • With SUPREME NUDGE, he worked on supporting a healthy lifestyle through supermarkets to combat non-communicable diseases such as diabetes.
