    Towards elimination of human African trypanosomiasis!
    Veerle Lejon is Directeur de Recherche at the Institut de Recherche sur le Développement in France (UMR 177 InterTryp, http://umr-intertryp.cirad.fr/). She works on development and evaluation of diagnostics for human African trypanosomiasis, with a focus on post-therapeutic follow-up, asymptomatic infections, potential applications for vaccine development and disease marker discovery. Veerle is coordinator of an EDCTP2 project on diagnostic tools for HAT, with partners from Belgium, Burkina Faso, DR Congo, Côte d’Ivoire, Guinea and the UK (http://www.ditect-hat.eu/).
