MY RESEARCH interests concentrate on galaxy formation and the large scale structure of the Universe. My models provide an accurate and concise description of the abundance and spatial distribution of galaxies and galaxy clusters in expanding world models.

In particular, I develop models of hierarchical clustering which use a variety of analytical (combinatorics, stochastic processes, point processes) and numerical tools. The model predictions are compared to simulations and observations. I have recently become interested in models where fragmentation also matters, as well as in various statistical estimation problems motivated by astrophysics.
