Leffler Ellen

Post-doctoral research associate

Research overview

Ellen works in Chris Spencer’s group and in collaboration with MalariaGEN on the analysis of human genetic variation data in the context of malaria. She is interested in the impact of selection and host-pathogen co-evolution on susceptibility to infectious disease. She currently works on investigating genetic association signals for susceptibility to severe malaria and characterising genetic variation in the Gambia. She is also using next-generation sequencing data to identify functional variation in loci at the interface between the human host and the malaria pathogen.
