October  2005:  Research position for CNRS at Nice University.
2004-2005: Visiting assistant professor at Purdue University.
2003-2004: ATER (teaching and research assistant) at Nantes University.
2000-2003: PhD thesis under the direction of Laurent Guillopé. Defense on june 16, 2004.

CV: vita (in french).

Research areas: spectral and scattering theory, differential geometry, PDE. 

Current research interests:

Scattering theory on asymptotically hyperbolic metrics and on geometrically finite hyperbolic manifolds, geometric and conformal related invariants.
Scattering and inverse problems for ACH metrics (incl. pseudoconvex domains, convex co-compact complex hyperbolic groups).
Small energy behaviour of resolvents, Riesz transform Lp boundedness.
Large time wave behaviour, trace formulae, zeta functions.
