I develop statistical models for use as priors in Bayesian methods for phylogenetic inference. In particular, I'm interested in divergence-time estimation -- e.g. modeling rate variation across the tree of life, diversification processes, and methods for incorporating information from the fossil record.


Time at MBL

Monday July 19 - Sunday July 30

2018 Course

July 22 - Evening lecture on divergence-time estimation

July 28 - Divergence-time estimation in RevBayes

All workshop materials will be made available on the RevBayes website: https://revbayes.github.io/workshops/woodshole2018.html
