I am interested in developing mathematical models describing the joint evolution of active and passive populations. We investigate two distinct descriptions: 

1. a continuous one with deterministic dynamics (i.e. a PDE system coupling fast-slow flows in porous media via Forchheimer-like equations coupled with diffusion via non-linear interaction terms),

2. a discrete one with Monte Carlo stochastic dynamics (i.e. a gas dynamics formalism involving two species driven by different dynamics competing via simple exclusion processes for the same lattice).

Our ultimate goal is to unite these descriptions into a multiscale, hybrid (coupled deterministic/stochastic) evolution system. We provide mathematical analysis and simulation results for parts of the proposed models.
