This project aims to study the behaviour of systems of long polymers in solution, and the effects of temperature, solvent and other environmental properties. Polymer models capture important physical properties of real-world molecules like DNA. This project will study the topology of polymer chains in tightly confined spaces. Knots and links hinder important biological processes like DNA replication, and this project will research how entanglement forms and how the biological mechanisms are used to manage it. The project is expected to have both important biological consequences and to enhance Australia's position as a centre for research in statistical mechanics.

本项目旨在研究长聚合物体系在溶液中的行为，以及温度、溶剂和其他环境特性的影响。聚合物模型捕捉了现实世界分子（如DNA）的重要物理特性。这个项目将研究聚合物链在密闭空间中的拓扑结构。结和链接阻碍了重要的生物过程，比如DNA复制，这个项目将研究缠结是如何形成的，以及如何使用生物机制来管理它。预计该项目将产生重要的生物学影响，并加强澳大利亚作为统计力学研究中心的地位。
