Dr Antoine Claessens
I am a Research Fellow on a joint LSHTM/MRC-Gambia fellowship from the MRC. After my PhD at Edinburgh University with Pr Alex Rowe and a post-doc with Pr Dominic Kwiatkowski at the Sanger Institute, I joined LSHTM in 2014. I'm mainly based at the MRC-Gambia in Fajara, The Gambia, West Africa.
My current research focuses on genomics of Plasmodium falciparum asymptomatic infection.
The Plasmodium falciparum population in The Gambia fluctuates between a high prevalence in the wet season (transmission season) to a low prevalence in the dry season (no transmission). This drastic environmental change likely selects parasites that are genetically better suited for one environment or the other. We regularly collect blood samples from asymptomatic volunteers, sequence P. falciparum genomes and compare allele frequency variations between pre and post-transmission seasons. I am testing the hypothesis that some parasite allele frequencies will be associated with survival over the dry season.
