Anisotropic Cosmological Solutions

I will present a general overview of some of my work which are concerned with cosmology based on various string theory idea. I will give detail of my recent work where, we present a class of anisotropic brane configurations which shows BKL oscillations near their cosmological singularities. Near horizon limits of these solutions represent Kasner space embedded in AdS background. Dynamical probe branes in these geometries inherit anisotropies from the background. Amusingly, for a probe M5 brane, we find that there exists a parameter region where three of its world-volume directions expand while the rest contract.
