Short summary of the research :
As a climate modeller, I studied very different climate contexts from “snowball earth” (800-600 Ma)  to more recent climate associate to the onsets of Sahara  and of Asian Monsoon (7 Ma). I am also interested by the relationships between climate and mountain uplift  and emergence of hominin .
My major focus concerning Quaternary are the shift between interglacial and glacial cycles  but also glacial climate variability .
