Osier is Visiting Professor of Malaria Immunology in the Nuffield Dept of Medicine at Oxford University, and a Principal Investigator at the KEMRI-Wellcome Trust Research Programme in Kenya and at Heidelberg University Hospital in Germany. She obtained her medical degree from the University of Nairobi, Kenya and her PhD from the Open University, UK. Osier’s research has found a strong correlation between the breadth and magnitude of antibody responses to multiple malaria parasite targets and acquired immunity to malaria. Osier designed KILchip ©, which is a custom Plasmodium falciparum high throughput protein microarray platform.
She also founded the SMART (South-South Malaria Research Partnership) network, a collaborative network of more than 20 international malaria research leaders that share resources in order to accelerate malaria vaccine development. Osier is a member of the Royal College of Paediatrics and Child Health UK and in 2019, she was appointed President of the International Union of Immunological Societies after having served as Vice-President for three years. She is a recipient of the Royal Society Pfizer Prize and the Sofja Kovalevskaja Award from the Alexander Humboldt Foundation.
