Dr. Marie Bradley is a Cancer Prevention Fellow with the Clinical and Translational Epidemiology Branch (CTEB) of the Epidemiology and Genomics Research Program (EGRP). In this role, she will undertake pharmacoepidemiological research in relation to the risk and progression of cancer associated with the use of routinely used drugs and the long term adverse effects of cancer treatments, such as the development of cardiotoxicities and second cancers.

Dr. Bradley is a pharmacist and, during her Ph.D. in Pharmacoepidemiology, she investigated the association between exposure to routinely used drugs, such as statins, proton pump inhibitors (PPIs), aspirin and non-steroidal anti-inflammatory drugs (NSAIDs), and pancreatic cancer risk and survival using the United Kingdom (UK) Clinical Practice Research Datalink (CPRD). Upon completion of her Ph.D., Dr. Bradley was awarded a 5-year post-doctoral fellowship in the Health Research Board Centre for Primary Care Research, a joint collaboration between Queen’s University Belfast, Royal College of Surgeons in Ireland, and Trinity College Dublin. Her post-doctoral research focused on investigating the prevalence and predictors of potentially inappropriate prescribing (PIP), among older adults, in the UK and Northern Ireland (NI) using CPRD and other smaller prescribing databases in NI. She was involved in designing and developing interventions to reduce PIP which were aimed at primary care physicians in Ireland.
