    RESEARCH PROJECT

    My research interests lie in Soft Matter, Rheology, non-Newtonian fluid mechanics, and droplet dynamics. The study of the channel flow of concentrated suspensions endowed with a yield stress is my primary project. On the side, I am working on the hydrodynamic drainage between droplets during the coalescence process in emulsions. Also, I am studying the effect of interfacial properties on droplet deformation in the linear flow under Stokes limit.
