Research Interests:

My research frames questions in a phylogenetic framework, to elucidate evolutionary relationships among plant groups with interesting geographic distributions or complicated morphologies. I have utilized two very different groups of flowering plants to address the questions above, members of the dicot tea family (Theaceae), and two families of the monocot ginger order: the prayer plant family (Marantaceae), and canna lilies (Cannaceae).

Current projects include:

Plastid Primers for Phylogenetics. I am always looking for faster evolving regions in the chloroplast genome for use in assessing relationships among closely related taxa. As a result, I have designed primers for dozens of non-coding regions in the large and small single copy regions of the chloroplast genome based on the complete chloroplast genomes of 16 flowering plants. These regions are largely new relative to those described by Shaw et al. (2005, 2007). This research was presented at Botany 2011 (abstract 619). You can access the primer sequences and information on utility of these regions at my Plastid Primers for Phylogenetics web page.

Recent projects include:

Guzmania (Bromeliaceae) fast evolving chloroplast and nuclear ITS sequence data. Molecular phylogenetics at the infrageneric level has progressed slowly for Bromeliads due to a lack of appropriately variable markers. Similarly, nuclear ITS (internal transcribed spacer) data have not been employed due to technical difficulties. Careful screening of dozens of plastid spacer and intron regions has identified a collection of quickly evolving regions that may prove valuable for many genera in the family. Technical difficulties with ITS were improved but may not be worth the time, effort, and expense due to low sequence variability.
