## Research

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 24 - Sunday July 30

## 2017 Course

Morning lecture slides and example scripts

- Hierarchical models and integrative Bayesian analysis (slides)
- Bayesian divergence-time estimation (slides)

Afternoon tutorial
