My current project focuses on studying phase separation in inhomogeneous fluids, which can provide an effective method for segregating pollutants from the fluid at a large scale. This research is being conducted using continuum approaches, such as density functional theory, which facilitate quick approximations for parameterizing the system. Additionally, the development of computational tools and packages that are less time-consuming and more energy-efficient for studying such systems is also part of the work. We further validate our models by applying more robust and sophisticated methods, such as dissipative partical dynamics, before conducting experiments with our collaborators.
