Will Freyman


I am a doctoral candidate and NSF Fellow in the Baldwin Lab at UC Berkeley. My research interests revolve around empirical and theoretical aspects of plant evolutionary genomics, computational phylogenetics, and biodiversity informatics.

Plant evolutionary genomics

Currently, I'm using phylogenomic approaches to study reticulate evolution in Chylismia (Onagraceae). I'm applying Chylismia data and simulations to test a composite likelihood approach I've developed that infers ancient introgression and hybridization events over phylogenies using coalescent probabilities.

Computational phylogenetics and modeling

I've worked on implementing ancestral state reconstruction functionality in the RevBayes project. In RevBayes I've also developed continuous-time Markov chain models of discrete character evolution, in particular chromosome number evolution. I'm broadly interested in mathematical models of evolution and applying them with Bayesian inference.

Biodiversity informatics

At UC Berkeley I've been part of the California Phylodiversity Project. Previously, working with non-profit and volunteer conservation groups, I developed open source web-based tools to help manage and assess conservation projects. I'm interested in building tools that visualize biodiversity data and help make conservation management more collaborative and transparent. Can we build useful tools for conservationists that incorporate metrics of phylogenetic diversity?
