Summary of Research

I am currently working on models and simulations of biofilms that can accurately capture the biomechanical response of biofilms to fluid flow. Biofilms are colonies of bacteria that grow on surfaces and are often interconnected through an extra-cellular matrix that contains cohesive polymers. Determining the material properties of biofilms, especially what leads to detachment and fragmentation of biofilms is an open question that has relevance to several application areas.
