Broadly my research group's interests are in theoretical biology, with a focus on evolutionary genetics and evolutionary theory.

Current projects in my research group are

[1] Developing ancestral graph methods to understand the evolution of multivariate diversity

[2] Multilocus selection in polyploids

[3] Plasmid population genetics

[4] Metagenomic theory

Students with interests in theoretical biology are welcome to contact me about undergraduate or graduate research.
