In 2010 he was an invited speaker at the International Congress of Mathematicians in Hyderabad and gave a talk Quadratic Julia Sets with Positive Area based on joint work with Arnaud Chéritat. In 2006 Buff and Chéritat received the Prix Leconte of the French Academy of Sciences for their collaborative work on Julia sets with positive mass; they proved the existence of quadratic polynomials that have positive Lebesgue measure. In 2008 Buff, Chéritat, and Pascale Roesch received a Young Researchers grant from Agence Nationale de la Recherche. In 2009 Buff became a member of the Institut Universitaire de France.
