I am postdoc at  KTH, Stockholm, supported by the Knut and Alice Wallenberg Foundation. I am working with Michael Benedicks on the entropy of unimodal maps.

I have obtained my PhD at the University of Paris-Sud, Orsay under the supervision of Jacek Graczyk. The subject of my thesis is the relation between dynamics and geometry of Julia sets of rational maps.

The slides (fr) of my talk at Jussieu Institute, Paris present the first two papers (with many pictures), after a short introduction to rational dynamics and geometry of Julia sets. The bimodal map construction that is the base of the third paper is present on the last slide.
