Professor Nick White is a Wellcome Trust Principal Research Fellow who chairs the Wellcome Trust Tropical Medicine Research Programmes in South East Asia. He has lived and worked in Thailand since 1980. His research focus is the pathophysiology and treatment of malaria. He has concentrated on characterising antimalarial pharmacokinetic-pharmacodynamic relationships to improve the treatment of malaria and reduce the emergence of resistance. This led to artemisinin-based combination treatment for falciparum malaria, and the change to artesunate for severe malaria. He has authored over 1000 scientific publications and 50 book chapters. He is on the Board of the WorldWide Antimalarial Resistance Network and Infectious Diseases Data Observatory, and he co-chairs the WHO GMP technical expert group on prevention and treatment of malaria and the WHO antimalarial treatment guidelines committee. He was appointed a Knight Commander of the Order of St Michael and St George (KCMG) for services to tropical medicine and global health in the 2017 New Year’s Honours.
