Janneke Verberk started her career (2015) as epidemiologist for the National Immunisation Programme at the National Institute for Public Health and the Environment (RIVM) in Bilthoven, focusing on seroepidemiology (PIENTER3) and rotavirus vaccination. In August 2018 she began working as PhD researcher at the Infection Prevention unit of the UMC Utrecht in collaboration with the department Epidemiology and Surveillance of the RIVM under supervision of prof. dr. Marc Bonten (UMC Utrecht), dr. Maaike van Mourik (UMC Utrecht) and dr. Sabine de Greeff (RIVM). She performed several multicenter studies investigating automatization of surveillance of healthcare-associated infections. Besides her work as a PhD candidate, she assisted in teaching of epidemiology to medical students and Infection Preventionists, and advised RIVM-PREZIES in national implementation of semi-automated surveillance. When in March 2020 the SARS-CoV-2 became pandemic, she started simultaneously working for the EU funded project Rapid European COVID-19 Emergency Research response (RECOVER) and for the seroepidemiological study PIENTER-corona of the RIVM.
