Dr Joel Tarning started his scientific research career in 2007 at the Mahidol-Oxford Tropical Medicine Research Unit (MORU) in Bangkok, Thailand. Since 2013, he has been leading the MORU department – Clinical Pharmacology, comprising a large and diverse team of 30 people. The main scientific directions within the department are pharmacometric data analysis, bioanalytical method development, drug quantification of clinical study samples, omics-based research, and medicine quality. His main research is focused on dose-optimisation in neglected tropical diseases, with a particular focus on vulnerable populations at risk of treatment failure and resistance development, such as children and pregnant women. His work on population pharmacokinetic-pharmacodynamic modelling of oral dihydroartemisinin-piperaquine in children with uncomplicated malaria, and intramuscular artesunate in children with severe malaria started the debate on new dose recommendations in young children, which resulted in revised WHO Guidelines for the treatment of malaria, 3rd edition (2015). He is a Professor of Clinical Pharmacology at the University of Oxford, UK (2016), and a visiting professor at the Faculty of Tropical Medicine, Mahidol University, Thailand (2016).
