Statistical methods
Rolf Groenwold's research focuses on the evaluation and development of statistical methods, with which we can better and more efficiently investigate the effects of medical treatments. He focuses on methods for observational (non-experimental) research of beneficial effects of treatments (effectiveness) as well as adverse effects (side effects).
Academic career
Rolf Groenwold obtained his PhD in Epidemiology in 2009 based on his thesis 'Quantifying confounding'. He conducted his PhD research within the Julius Center for Health Sciences and Primary Care, UMC Utrecht. After his PhD he was appointed there as assistant professor and later as associate professor. In 2017 he was appointed at the LUMC in Leiden. Since 2018 he holds a position as Professor of Clinical Epidemiology. The title of his inaugural lecture is 'Read the medication label before use'. He has received a ZonMW Veni grant, a ZonMW Vidi grant and an LUMC fellowship, among others.
