We are interested in studying physical phenomena such as self-assembly, aggregation, gelation and crystallization of soft matter, in general, using computational modeling techniques. We use Monte Carlo, Molecular Dynamics, Rare event simulations, etc. extensively. We are also inspired to develop quantitative models by deterministic and stochastic approaches to understand the mechanisms of growth of colloids/nanoparticles of various shape and composition, and to investigate biophysical process such as protein folding. To this purpose we use stochastic kinetic Monte Carlo and population balance equations.
