Biography:
Benedikt Ley is a public health expert specializing in diagnostics, malaria, and glucose-6-phosphate dehydrogenase (G6PD) deficiency. He began his career in 2008 with the University of Vienna (Austria), working in Bangladesh on infectious diseases along the Bangladesh–Myanmar border.
In 2009 he joined the International Vaccine Institute (Korea), based in Zanzibar and subsequently in Kenya, focusing on typhoid fever. In 2012, Benedikt moved to the Institute of Tropical Medicine in Antwerp (Belgium), where he worked on Salmonella spp. infections. He completed his PhD in 2013 with the University of Vienna, focusing on the diagnosis of cholera and typhoid fever.
Benedikt joined the Menzies School of Health Research in 2014, where he currently holds the position of Principal Research Fellow and Senior Lecturer. His research focuses on the interaction between G6PD deficiency and the malaria parasite Plasmodium vivax in the human host, assessing G6PD deficiency as a risk factor in standard malaria treatment, and evaluating diagnostic tests for their field use, particularly in remote settings. He is also actively involved in teaching in the Menzies Postgraduate Public Health programs at Charles Darwin University.
