Dynamical and Statistical Modeling of Biological Systems

Due to its intrinsic nonequilibrium nature and complexity, biological systems have become an exciting field for applying dynamical system and statistical methods to discover its underlying principles. The main theme of this minisymposium is to understand large-scale collective behavior from simple microscopic rules. The biological systems covered in this session range from RNA mutation, DNA sequence matching, protein folding to flocking dynamics. Simple microscopic rules based on experiment are used in modeling these biological systems. Continuum models can also be constructed for some cases in a coarse-grained level and analytical insight is often gained by comparing the biological systems to well studied physical systems.
