In November 2019, he graduated from the Radboud University in Nijmegen, obtaining his Master’s degree in Biomedical Sciences, specializing in conducting Epidemiological Research. In October 2020, he became a certified Epidemiologist A, following official registration by the Dutch Epidemiology Society (Vereniging Voor Epidemiologie). After obtaining his Master’s degree, he started as a PhD Candidate in the group of Prof. Dr. Winette van der Graaf and Dr. Olga Husson at the Netherlands Cancer Institute (NKI) in January 2020. His doctoral research will focus on the epidemiological aspects of cancer in Adolescents and Young Adults (AYAs, aged 15‒39 years). By investigating long-term cancer trends and second cancer risk in AYAs during his PhD, he aims to narrow down the gap in knowledge and hopes that the knowledge gained will positively contribute to improving health outcomes and medical care received by this distinct patient population within the oncology domain.
