What is it about?

Transport of light heat and electricity in mixtures depends a lot on how the various parts are arranged. I was able to show a new faster way to calculate this, and used this to look at random honeycomb structures, finding that they are surprisingly similar to regular honeycombs.

Why is it important?

Random honeycomb structures (like plant cells) are common in nature, and it's useful to know how well they transport light, heat, and electricity (among other things). Existing methods to calculate transport are quite slow, but I was able to show how to do this much faster, and was able to show that their transport is surprisingly similar to (and in some cases better than) their regular counterparts.


This followed on very quickly from some great work I did with Marc Gali.
