My current focus is on relating social cognition to brain size, such as social learning, social recognition and memory and contest resolution. I have also done experiments on predator responses of these fish, such as predator inspections and risk taking behavior.
I'm interested in using strong quantitative analysis of animal behavior, such as video tracking and social networks.
I also do some work in R. I've written/am writing:
- The 'phylopath' package for phylogenetic path analysis. It's currently on CRAN (https://cran.r-project.org/web/packages/phylopath/index.html).
- The 'trackr' package for analysis and visualization of video tracking data. It's currently in development, and can be found on GitHub (https://github.com/ax3man/trackr).
