Research Interests

In my research I use phylogenetic methods to study evolutionary relationships, character evolution and biogeography in the blueberries (Vaccinieae), a morphologically complex and diverse clade from the heath family (Ericaceae). Phylogenies are diagrammatic representations of the evolutionary relationships within a group and are a powerful tool for studying the diversification patterns of lineages and hypotheses of homology and character evolution. I have examined evolutionary relationships in the blueberry group using both large and small scale analyses of DNA sequence data and plant morphology in order to identify major clades within the tribe and assess the monophyly of genera. My research incorporates recent advances in computing and data-basing capacity and faster more efficient methods for amplification and sequencing of DNA sequence data.
