Research interests

Since the beginning of my scientific career, I have been interested in understanding the role of inflammation in the pathogenesis of severe infections in general, and of fungal infections in particular. My research focus is directed towards understanding the recognition of pathogenic microorganisms by pattern-recognition receptors, as well as the cytokine response induced during infection. We have described the first comprehensive model of recognition of a fungal pathogen by the innate immune system, we had an important contribution to the elucidation of the mechanisms responsible for inflammasome activation in various cells types and we also identified novel immunodeficiencies leading to specific susceptibility to fungal infections such as dectin-1 deficiency and STAT1 defects in chronic mucocutaneous candidiasis. A major area of interest during the last years was the discovery of innate immune memory induced by infections or vaccinations, a process identified and described as ‘trained immunity’. ​In addition, we are currently involved in a major systems biology effort to understand variability of human immune responses within the Human Functional Genomics Project (see
