Catriona Waitt is a Professor of Clinical Pharmacology and Global Health at the University of Liverpool, and has been based at the Infectious Diseases Institute, Makerere University College of Health Sciences since 2014. Her research focuses on drug dosing, efficacy and safety in complex and understudied populations, particularly pregnant and breastfeeding mothers and their infants. Her work draws together clinical trials, observational clinical studies, pharmacometrics, social science and public engagement and involvement. Because of the importance of pharmacometrics to study design and interpretation in these complex populations, her team emphasises continued capacity building in the discipline, including with the launch of the Uganda Chapter of Pharmacometrics Africa in 2021.
