The soft matter research program is mainly inspired by our experience with interesting but non-intuitive phenomena with everyday materials, such as peeling of paint, sticking of particulate matter to surfaces, formation of cloud, structure and dynamical response of a sandpile. Questions of basic and general nature are extracted from them and experimental methods are devised in order to find precise answers about them in model systems that retain the essence of the original observations. The experimental systems typically consist of building blocks that are larger than atomic dimensions, from ten nanometers to centimeters, both in and out of mechanical and thermodynamically equilibrium. The investigations are aimed to provide deeper understanding of the world around us. We use experimental tools like optical tweezers, various types of rheometry and high speed imaging techniques. We also develop new techniques, experimental protocols and their interpretive framework. The broad aim is to ask interesting questions and devise novel ways to study them.
