Research

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.

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 visual key. 

I have also developed free, open source visual learning software that can be downloaded here. It is easy to customize for your own course or study options.
