Stochastic population models and combinatorial stochastic processes arising from ecology, epidemiology and population genetics.
- Mathematical: density-dependent population processes, branching processes, Fleming-Viot processes, coalescent theory, and large deviations.
- Biological: demographic stochasticity, community genetics, robustness & adaptability, molecular evolution, and phylogenetics.

- Here's a Transport Canada case study of BikeShare, a bike lending program I co-founded. From 2001-2006, it was North
America's largest bike-sharing program.

- For the sake of my sanity, I would encourage everybody to read this. You should watch this too.
