Electrokinetics & biofilms: External electric fields can delay biofilm formation on certain substrates. The image shows the flocculation of enteroaggregative E. Coli. in response to the  presence of an external electric field. This is an important discovery …

Biofilms as soft matter: On moist surfaces, several bacterial species can form biofilms. These biofilms are colonies of bacteria that are encased in extra-cellular polymeric substances (EPS). These biofilms are excellent examples of natural soft matter. They possess …

Hydrodynamics & biofilms: We are studying biofilm formation inside porous microfluidic mimic devices. Under certain hydrodynamic conditions, fluid shear can cause the appearance of filamentous biofilms, called streamers. Streamers are act as precursors …
