It is impossible to understand quantitatively how organisms function without theoretical modelling, and modelling of biological processes generally leads to novel development of theoretical concepts and tools. Therefore, biological physics is not only one of the most exciting areas in science at the moment, it also provides a fertile ground for expanding the knowledge horizon in both biology and physics. For instance, active matter physics, stochastic thermodynamics, physics of information processing, and non-equilibrium phase separation are all recent examples of how novel physics has arisen from tackling problems that were mainly motivated by biological phenomena. At Imperial College, we possess the core strength in developing the theoretical tools to answer important biological questions in all of the key areas of biological physics.
