We combine theoretical, numerical and experimental tools, to study how the fundamental processes of flow, transport and mixing shape environmental systems characterized by confinement. We pay particular attention to the coupling between some aspects of microbial life, fluids motion, solutes and colloidal transport and mixing dynamics. The two main research axes we develop are reactive transport and filtration by heterogeneous porous media.
We develop and fabricate transparent microfluidic devices to reproduce a confined environment (such as soil or a filter) that we observe using time-lapse video-microscopy and image processing. We also apply computational and theoretical methods to understand and upscale the variety of flow- and mixing-driven scenarios that we investigate.
