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
 Developing ancestral graph methods to understand the evolution of multivariate diversity
 Multilocus selection in polyploids
 Plasmid population genetics
 Metagenomic theory
Students with interests in theoretical biology are welcome to contact me about undergraduate or graduate research.
