Research Interests: Theoretical Cosmology, Astrophysics & Gravitation
Large scale structure
cosmic web, matter and halo correlation functions, redshift space distortions
Dark matter dynamics and self-gravitating systems
perturbation theory, spherical collapse, semiclassical methods for classical dynamics, Vlasov-Poisson and Schrödinger-Poisson equations
Collapse in 1+1dimensional phase space showing the transition from a flat phase space sheet to a bound dark matter structure modelled by solving the Schrödinger-Poisson equation (blue contours) and the Zeldovich approximation (red dashed line) 
Time-evolution of a wave function solving the free Schrödinger equation in 1D. This is a semiclassical analogue of the Zeldovich approximation. Shell-crossing forms multiple streams that manifest as interference patterns.
