Research Interests

Our research efforts focus on systematic and evolutionary studies of various plant groups such as the Acanthaceae, Asteraceae, Fabaceae, and Orchidaceae. In concert with traditional systematic investigations we make extensive use of gene sequence data and endonuclease restriction site data. We have a well-equipped laboratory for molecular work. In addition, we are interested in the Louisiana and Gulf Coast floras and conservation biology.
