In this thesis proposal, I propose to explore physical network systems by developing network theories that aim at describing and explaining properties of physical networks, as well as analyzing specific real-world physical network systems. The first project is on the tangledness of physical networks embedded in 3D space. In the second project we explore a specific physical system, the Drosophila larval brain system, and design the network extraction method that best preserves the level detailed information and the relations between the components in the system. The third project focuses on the link trajectories in physical networks, and aims at finding a method to describe and explain the different trajectories of links in physical systems.
