The interface between biology and physics is getting increasingly blurred.  The main reasons for this are the development of new quantitative techniques to study biological systems and a migration of physicists, mainly from areas like soft matter and statistical physics, to biology.  As a result more and more complex biological phenomena are coming within reach of a physical description. The dynamics of the cytoskeleton is one such problem. Our goal is to improve our understanding of the mechanical and dynamical properties of this complex network of biopolymer filaments, which can interact with molecular motor proteins to generate a very rich variety of "active" phenomena. These include morphological changes, instabilities, and active mechanics. Please see the webpage linked above for more details.
