Olivia Keiser is an epidemiologist and scientific group leader at the Institute of Global Health (IGH), at the University of Geneva, Switzerland. She studied biology at the University of Basel, with a focus on epidemiology, and then moved to Lausanne where she worked at the data centre of the Swiss HIV Cohort Study for several years. While working in Lausanne, she completed a Master in Statistics at the University of Neuchâtel. In 2006, Olivia joined the Institute of Social & Preventive Medicine (ISPM) at University of Bern, where her PhD work focused on outcomes of antiretroviral therapy (ART) in the IeDEA Southern Africa collaborative networks. She gained first-hand experience of the scale-up of ART in Malawi and South Africa. After earning her PhD in 2009, Olivia was appointed group leader of the HIV/Hepatitis group at ISPM.
After receiving an assistant professorship in 2017, Olivia moved with her group to the IGH in Geneva and began collaborating with IeDEA in Central and West Africa. Olivia’s research group takes an interdisciplinary approach that combines mathematical modelling (including cost-effectiveness analyses), data- and text mining, systematic reviews, and qualitative research techniques. The focus is on HIV, Tuberculosis, influenza and Covid-19 both in Switzerland and abroad.
