I study plant evolution from a structural and developmental standpoint, and have developed methods of improving morphological characters in studies of plant evolution. I have also developed innovative methods of computer-based visual learning. In addition to studying plant structure and development, students in my lab have worked on organic methods of weed control, and air pollution effects on pines.

We have recently completed the first completely visual keys to a group of organisms, the Fagaceae of the Southeastern United States. Click here to go to the on-line Bayesian visual key. The principles behind this key are descried in Kirchoff et al. (2008). A paper key to the family has just been submitted for publication. A link will be posted here when it appears in print.
