About the Workshop:

Recent computational and modeling advances have produced methods for estimating species trees directly. Accurate estimates of phylogenetic relationships can often be extracted from genetic data with these new appraoches, sometimes with less data, by directly modeling the causes of discordance in topology and branch lengths among gene trees. Such inferences are commonly impossible under the traditional phylogenetic paradigm because of the potential for the idiosyncrasies of gene trees to obscure the actual history of species divergence.

We are offering this workshop to increase the visibility and use of these methods, to address a number of significant challenges to estimating species trees, and to assure that the advantages these methods offer will reach a broad community of users.

This workshop has been made possible by funds generously provided by the National Science Foundation, the Mathematical Biosciences Institute, the Department of Statistics and the Department of Evolution, Ecology, and Organismal Biology at Ohio State University.
