Research:

My research interests concentrate on studying the large-scale structure of the universe as determined by different probes, such as the clustering of galaxies, weak gravitational lensing and other deep surveys.

The goal is to understand the nature of primordial fluctuations (hopefully shedding light on the physics of inflation), the source of the observed acceleration of the universe (dark energy or modifications of general relativity), and the relation between the dark matter and the galaxy distribution (to learn about galaxy formation).
