ERC Postdoc


Room: 6M33 Huxley Building
I am an ERC post-doc, working on the generalization of Denjoy theory to higher-dimensional tori with S. van Strien. This is my CV


During the second term of the academic year 2017-18, starting January 17, I tought the course "Advanced topics in Dynamical Systems", M5PA38.

I covered the basics of the theory of homeomorphisms and diffeomorphisms of the circle: from the study of rotations to Poincaré classification, to Denjoy theory, and concluded with the K.A.M. theorem.


My current research interests include
  • Linearizability of smooth pseudo-rotations in tori
  • Cohomology of Dynamical Systems
  • KAM Theory
  • Dynamics of Quasi-periodic cocycles in compact groups
The list of my publications on MathSciNet is here, my profile on GoogleScholar is here and the list of my preprints on the arXiv is here.


  • Global aspects of the reducibility of quasiperiodic cocycles in semisimple compact Lie groups, Mémoires de la SMF 146 (2016). arXiv preprint here
  • Differentiable Rigidity for quasiperiodic cocycles in compact Lie groups, JMD, vol 11 (2017), p. 125-142. arXiv preprint here
