Cell biologist in host-pathogen interaction with a focus on lipids of  mycobacteria and phagocytes

The main objective of my current research is to understand the role of lipids in Mycobacterium tuberculosis interaction with host cells in order to propose new strategies for TB control. In particular, I am interested in degradative processes involving lysosomes such as phagosome maturation, canonical and non-canonical autophagy.
