Trained as a nutrition scientist (Molecular Nutrition, Wageningen UR) and epidemiologist (Nutritional Epidemiology, Erasmus University), my current research and teaching focus on the impact of nutrition, lifestyle other environmental factors on population health across the lifecourse. I lead the Nutrition & Lifestyle research group and I am vice-chair of the Department of Epidemiology at Erasmus University Medical Center. My team's research involves systematic reviews and meta-analyses; and analyses of data from cohort studies and biobanks, including the Rotterdam Study and Generation R Study cohorts in which I am principal investigator.Since 2023, I combine my role at Erasmus MC with a research fellowship at the Meta-Research Innovation Center at Stanford (METRICS), where I focus on improving research methods and meta-research in the fields of nutrition and lifestyle epidemiology.I have supervised many PhD students (11 graduated) and postdocs, have published over 200 scientific papers and book chapters (H-index 49), and teach courses on research methodology and preventive medicine at various universities and research institutes.Publications: https://pubmed.ncbi.nlm.nih.gov/?term=voortman+t+not+voortman+tpORCID: https://orcid.org/0000-0003-2830-6813Team: https://www.erasmusmc.nl/en/research/groups/nutrition-and-lifestyle-epidemiology
