I am a postdoc (recently an NSF PRFB fellow; now a postoctoral associate) at the Florida Museum of Natural History, working primarily with Robert Guralnick and Douglas and Pamela Soltis.
My research broadly uses phylogenies to answer evolutionary and ecological questions in a number of areas.
Evolution of nitrogen-fixing symbioses: I am involved in work using phylogenetic approaches and natural history data to elucidate the origins and phenotypic-ecological associates of multiple origins of nitrogen-fixing symbioses in the nodulating clade (>30,000 species, Fabales + Rosales + Cucurbitales + Fagales).
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, mostly derived from historical specimens, and current DNA infrastructure in GenBank, SRA, and 1KP.
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.
