The project aims at establishing a unified framework, currently lacking in the literature, to bridge the fragmented understanding of interfacial rheology in particle-stabilized emulsions and foams—spanning both introduced colloidal systems (such as silica and polystyrene) and in situ crystallizing species (such as monoglycerides and proteins). On the experimental and instrumentation spectrum, the work will address the critical technical challenge of real-time visualization of interfacial structural evolution under active deformation by designing and developing custom, in-house experimental setups for simultaneous high-resolution imaging and rheological characterization. The project will integrate theoretical modeling, high-fidelity simulations, and novel experimental diagnostics. Though strongly grounded in numerical and analytical formulation, the candidate will be deeply involved in hands-on development and validation using the state-of-the-art experimental facilities within the lab.
