Introduction to Chris Randle

Chris is a Ph.D. candidate in the Wolfe Lab working on the systematics of Harveya (Orobanchaceae), a holoparasitic plant genus distributed in southern Africa. Chris will be doing a revision of the genus in addition to molecular phylogenetics and studies of the molecular evolution of photosynthetic genes -- specificially the nuclear-encoded small subunit of Rubisco and plastid-encoded large subunity of Rubisco.

Here are some pictures from our field trip to South Africa taken during our field season of 1999.
