My research focus is the development and implementation of mathematical models for the study of diversification processes from phylogenies. I am interested in birth-death processes, a class of models which represent the speciation and extinction processes through time and across species. In particular, I have worked extensively on rate-heterogeneous birth-death models, which represent variations in diversification between different species or groups. I have also worked on models integrating fossil information with extant species to build combined phylogenies and obtain better estimates of past diversification dynamics. My research focuses on Bayesian phylogenetic inference, and I have contributed to the phylogenetic inference frameworks BEAST2 and RevBayes.
