I am currently an NSF postdoctoral fellow at the Florida Museum of Natural History, under Robert Guralnick and Douglas and Pamela Soltis.
My research broadly uses phylogenies to answer evolutionary questions in a number of areas.
Ancestral niche space: I am interested in developing new methodologies for using niche models with phylogenetic and phenotypic information to answer questions about niche shifts in a quantitative framework. These include the frequency and tempo of niche shifts in deep time, and the projection of ancestral niche parameters onto estimates of past climate.
Phylogenomics in the Saxifragales: I am currently developing a large phylogenomic supermatrix to cover more than half of the angiosperm order Saxifragales, an ancient, isolated radiation of ~2400 species, integrating across newly developed target-enrichment data and current DNA infrastructure in GenBank, SRA, and 1KP. This has resulted in ~700 taxa with phylogenomic data (~80% museum specimens, as old as 112 years); using supermatrix approaches we expect to cover well over half the order.
Hybridization: My PhD research organism is a model system for ancient hybridization, and still stands as one of the most prolific examples of historical introgression. I am using phylogenomic information and recently developed analytic approaches to detect these patterns of introgression and rigorously falsify alternative explanations for differing genome histories.
Species delimitation: Phylogenetic and comparative research generally presupposes species boundaries are known, an assumption that can be problematic given the biology of organisms of interest. I have worked in "sky island" systems in Heuchera to elucidate species boundaries using classical taxonomy, integrative datasets, and modern model-based approaches to assess lineages. I am currently working in some other problematic plant groups to clarify species boundaries and small-scale biogeographic relationships in other parts of North America.
