Research Interests

 Her research interests are in clinical trials, risk-benefit decision making for medicines, and the utility of Bayesian approaches in these areas. She has led the benefit-risk workstream of the IMI-funded PROTECT project, bringing together academic, pharmaceutical, regulatory and patient expertise to determine best practice, and innovate on both underpinning methods and communication of the benefits and risks of medicines.
