The goal of our group is to uncover mathematical laws that govern the living world. The 21st century has seen an explosion of quantitative data in Biology and one of the great challenges is to develop equally quantitative models that are capable of explaining all this data; for such models to be useful they must also provide experimentally testable predictions. If physics is the science that seeks to describe Nature using the language of mathematics then physical biology is that part of physics that concerns itself with the living world.
