Our research focuses on problems in the area of complex fluids such as suspensions, emulsions and foams. We are interested in understanding how the microscopic properties and structure of complex fluids determine their flow behavior. A better understanding of such a connection enables engineering of materials with desired end properties. Using theory and a host of advanced experimental techniques, we investigate a variety of complex liquids including paints, coatings, ceramics, adhesives and polymer solutions with a goal to improve their performance. More recently, we have been involved in collaborative projects to build biomedical devices for resource constrained settings, such as rural India, that require a sound knowledge of colloids, fluid mechanics and electronics.
