We will eventually write a survey paper. Here are the technical papers so far:

- Uniform Multicommodity Flow through the Complete Graph with Random Edge-capacities (with C. McDiarmid and A. Scott)
- Edge Flows in the Complete Random-Lengths Network (with S. Bhamidi).
- Cost-volume relationships for flows through a disordered network
- Optimal flow through the disordered lattice
- Optimal spatial transportation networks where link-costs are sublinear in link-capacity.
