My research is primarily in Mathematical Biology, and more specifically in Phylogenetics. It focuses on theory and methods for inferring relationships between organisms from biological sequences such as DNA or proteins. Most recently it has moved from finding evolutionary trees to more difficult problems where hybridization or other forms of horizontal gene transfer results in network relationships, and the signal of these is confounded with population genetic effects captured by a coalescent model. In addition to drawing on probability, discrete math, and modeling, my work often uses an algebraic geometry perspective and computational algebra tools.
