Soft Matter & Living Systems

You may have heard of soft materials, but what exactly are they? Examples include a wide range of materials from car tires to food, cream and foams. They are soft enough that their properties and structure are, curiously, determined by entropy — the thermodynamic law that dictates that disorder rules! Understanding these materials and their synthesis and governing principles has implications for technology development and for understanding the greatest mystery of soft matter — Life.

Living systems is the area of study in which materials meet life and biology, from the perspective of the physical scientist. Life consists of materials that are undergoing dynamic change driven by biochemical energy. How can the phenomena of life — replication, motility, robustness — be understood in a set of equations, or replicated in designed, engineered systems? The answer to these questions will establish new technologies for diagnostics, pharmaceuticals, and predictive therapies.
