My research interests center around resolution and analysis of nonlinear inverse problems :
- estimation of parameter in partial differential equations (heat, transport through porous media, wave propagation)
- numerical resolution by local optimization algorithms (problem of local minima, multiscale and adaptive parameterization, reformulation via duality, regularization)
- geometrical methods for the analysis of nonlinear least squares problem (projection on non convex sets)
- mathematical modeling and numerical resolution of flow through porous media.
