Soft matter physics studies systems that are mechanically soft such as liquids, colloids, polymers, foams, gels, granular materials, liquid crystals, and various biomaterials including proteins and membranes. These materials share common features in which thermal fluctuations and entropy effects are important and quantum effects are negligible. These materials display a broad range of interesting microstructures and phase behaviors and have a myriad of applications in the materials, food, paint, and cosmetic industries as well as medical technologies. Soft matter is a relatively new and rapidly evolving interdisciplinary research field across physics, chemistry, chemical engineering, materials science, mechanics, biology, and environmental science. Pierre-Gilles de Gennes, who received the Nobel Prize in physics in 1991, was awarded for his research in soft matters. Currently, six research groups in our department work on colloids, polymers, simple and complex fluids, electrorheological fluids, microfluidics, and biological materials, and explored their equilibrium structures and dynamics and far-from-equilibrium states.
