In recent years, Bayesian total-evidence dating has emerged as one of the premiere strategies for dating phylogenetic trees. However, in practice, total-evidence dating requires a great deal of biological, paleontological, and statistical expertise. Our workshop is intended to empower phylogeneticists interested in using total-evidence dating by providing: 1) a solid foundation in relevant topics in statistical phylogenetics; 2) discussion of empirical considerations, in particular how to deal with morphology and the fossil record, and; 3) hands-on experience with software, particularly RevBayes.

The course will begin on March 2 and run for 5 weeks (ending week of March 30). Each week, we will discuss a particular topic related to total-evidence dating (Wednesday 10 AM), provide experience with related methods with relevant hands-on tutorials (to be done throughout the week), and hold office hours to discuss the weekly topic and to help with practical issues that arise during the tutorials (Friday). See our Syllabus for more details about the topics covered each week.
