Prof. Catriona Waitt is a clinical pharmacologist from the University of Liverpool who has been at IDI since 2014 undertaking a Wellcome Clinical Research Career Development Fellowship. Her research interests are the dosing and safety of drugs in special populations who cannot be easily studied in conventional clinical trials, including pregnant and breastfeeding women and their infants, children and adolescents, patients with severe intercurrent illnesses and potentially interacting medications and vulnerable patients in outbreak settings. Her research programme encompasses intensive pharmacokinetic studies, clinical trials and sparse data collection from vulnerable populations with pharmacokinetic modelling to explore differences in drug exposure between individuals and populations.
