About myself

· I am currently a Marie Curie Fellow (Intra-European Fellowship within the 7^th European Community Framework Programme, Project ANERAUTOHI, grant agreement number PIEF-GA-2009-25271) at ETH Zürich.

· I have a permanent position (Maître de Conférences Habilité à Diriger des Recherches namely tenured assistant professor) at Université Bordeaux 1 since September 2005.

· I was formerly a postdoctoral fellow at Université de Montréal (Québec, Canada) under the direction of A. Granville.

· Before that, I did my thesis at Université de Montpellier 2 (France) and my advisor is P. Michel.

· Of course, my mathematical research is in the area of analytic number theory but I also have some knowledge of the theory of automorphic forms and I plan to enlarge my skills especially in ergodic theory.

My current attempts

· I am still trying to improve the results of my thesis that is to say essentially increasing the effective length of the mollifier via harmonic analysis (spectral method) and/or ergodic techniques.

· I get recently interested in discrete quantum chaos on quantum graphs, especially these induced from interval exchange maps.

· I get recently interested in the analytic aspects of GL(3)-automorphic forms and in particular the infinite norm of automorphic forms in the eigenvalue aspect jointly with Roman Holowinsky and Emmanuel Royer.

· I get recently interested in the analytic aspects of GSp(4)-automorphic forms jointly with Harald Helfgott, Emmanuel Kowalski and Abhishek Saha.
