- Transport of bacteria and colloids, and formation and growth of biofilms in heterogeneous environments: Microbes often live in crowded and heterogeneous environments, from the human gut to soil. To survive and flourish in such dynamic environments, they have to adapt strategies to avoid harmful chemicals and find nutrients. We therefore need to understand how microbes optimize and utilize their chemotactic response in the presence of dynamic spatiotemporal fluctuations in their environment.

- Fluid-fluid displacement and interfacial instabilities in confined and disordered media: Interfacial flows are ubiquitous in nature and technological applications, from dripping faucets to the storage of CO2 underground. To control these flows and predict their outcome, we need to understand how fluid-fluid interfaces behave and deform, in particular when they are confined in narrow spaces. In confinement, the interactions between the fluids and the surrounding solid surfaces become important. While these interactions are typically nanometric in range, they can influence the dynamics on much larger length scales. 

- Phase change and phase separation phenomena in multicomponent mixtures: The dynamics of evaporation and condensation in pure liquid drops and thin films is relatively well understood. However, most liquids used in technological applications are a mixture of multiple components. These components often have different properties and might even phase separate under certain conditions, leading to significant departure from the behavior observed in pure liquids.
