Research interests: I am interested in evolutionary relationships among flowering plants and how those relationships help us to understand biological processes. Research in my lab uses molecular phylogenetic methods to reconstruct the evolutionary history of groups of plants. These tools can give us insight into diverse evolutionary patterns and processes such as hybridization, chromosomal evolution, species diversification and timing of developmental changes. Please see the lab web page for more information on people and projects in our lab.

Research opportunities:Interested students can learn useful techniques such as DNA extraction and purification, PCR amplification, cloning and sequencing. They can also gain experience in phylogenetic methods (e.g. sequence editing, alignment and analysis).
