Main research interests 

We study how infectious agents develop intricate mechanisms to hijack the genetic and epigenetic machinery of their host cells to change phenotypic states. We investigate how the intracellular parasite Theileria hijacks host signaling pathways to maintain cell transformation. We recently identified epigenetic events in the host cell nucleus that are induced by the intracellular parasite and we also study epigenetic regulators of the parasite genome. The Theileria-infected leukocytes serve as a model to explore the plasticity of cellular phenotypes, the determinants of cell identities and the evolutionary strategies of interacting cellular systems.
