Dr Elsa Leger



Since February 2015, Elsa has been a postdoctoral researcher in the One Health Project ZELS (Zoonoses and Emerging Livestock Systems) on the epidemiology, evolution and prevention of Schistosoma hybrids. Her research focuses on populations at risk and transmission dynamics of infection with novel zoonotic hybrid schistosomes in sub-Saharan Africa and how these parasites can influence epidemiology, evolution and clinical outcome of schistosomiasis. She is leading major and intensive fieldwork in Senegal and Niger and conducting molecular laboratory work using multilocus approach.

In 2008, she obtained a BSc in Biology at the Aix-Marseille University in France and in 2010, a MSc in Biology with a major in evolutionary and behavioural ecology at the University of Burgundy (Dijon, France). During her master’s degree she studied for two years the influence of larval stage development of an acanthocephalan parasite on the behavioural manipulation of the intermediate host and the predation risk by fish (definitive host).

In December 2013, she completed her PhD in Montpellier, followed by a first postdoctoral position there in 2014. Her doctoral and postdoctoral research focused on vector-host-pathogen interactions. She evaluated patterns of host-associated genetic divergence in Ixodes ricinus tick populations and the impact of host specialisation of the tick on the transmission of the bacteria Borrelia burgdorferi sl (responsible for Lyme disease in Humans). She combined large fieldwork sampling, molecular analyses and experimental approach.
