At the moment I'm working on species delimitation. Basic problem: given genetic data from individuals eg a,b,c,d,e, infer how they cluster into species. Is it ab+cde or a+be+c+d or...? The approach is Bayesian, and it samples from the posterior using the Monte Carlo Markon chain technique. Right now I'm working on a package called [STACEY](http://biorxiv.org/content/early/2014/12/11/010199) for [BEAST2](http://beast2.org/). More info at [my website](http://www.indriid.com).
