Current Research Interests

* General topics :
Dark energy, gravitational lensing, dark matter, general relativity.

* More precisely :
- measure of distances in cosmology (perturbations, type Ia supernovae),
- gravitational lensing theory & simulations (weak and strong lensing),
- averaging problem of cosmology (non-linearity of general relativity),
- interactions between matter structures and space-time geometry.
