Medications are an essential aspect of health care. The PharmacoEpidemiology & Drug Safety (PharmaSafe) research group generates real‑world evidence on the safe and effective use of medications, with a strong focus on health data analyses and pharmacoepidemiology.

We are a multidisciplinary team with expertise in pharmacoepidemiology and drug safety, pharmaco(epi)genetics, biostatistics, causal inference, machine learning, and pharmacotherapy. By leveraging large-scale health data, such as national health and prescription registries, electronic health records, and population-based cohorts, we study how medications are used and how they affect patient outcomes across the life course and in vulnerable populations.

Using advanced epidemiological and statistical methods, we address questions that are difficult or impossible to study in randomized controlled trials (RCTs). Our research includes monitoring medication use and safety in pregnancy, evaluating vaccine safety and effectiveness, conducting methodological research, and analysing genetic and epigenetic contributions to medication response and adverse effects, as well as examining patient perceptions and experiences with medicines.
