Research: Disease ecology and evolution
Broadly, my research focuses on the ecology and evolution of diseases. This topic provides both an exceptional model for many areas of evolutionary ecology due to their rapid dynamics, and has strong applied relevance for human, animal and plant health and conservation. My main focus has been on understanding what drives the emergence of pathogens in new host species. I am currently working on an emerging human disease, Chagas. I am interested in the fundamentals of drivers of pathogen emergence. Using the model of Chagas disease with the wild vector system, I intend to find what is the importance of adaptation in disease emergence, which is crucial for understanding when and where disease may arise.

I am teaching in the biology department at Paris Sud, Orsay.
