Hi, James! All that sounds great. I wrote a bit about [information theory in evolutionary game theory and other aspects of biology](http://math.ucr.edu/home/baez/bio_asu/). I'd like to do more, but I'm getting spread a bit thin. My student Brendan Fong wrote a nice paper about [category theory and Bayesian networks](https://arxiv.org/abs/1301.6201), so the theme of causality is also starting to show up in category theory. There's a lot to think about around here!
