Professor and Department Chair
Expertise: Regulation of transcription and protein-DNA interactions
Currently, I have two research topics: RNA polymerase III transcription in the budding yeast Saccharomyces cerevisiae and the use of ribosomal RNA secondary structures in cyanobacterial systematics. Yeast work has focused on the role of Nhp6 in synthesis of tRNA and the U6 small nuclear RNA. This work utilizes both biochemical and genetic techniques in this simple eukaryotic model organism. The cyanobacterial work is done in collaboration with Jeff Johansen. Here, we amplify, clone, and sequence regions of the ribosomal RNA operon that interact to form the secondary structure of the unprocessed transcript. This work may shed light on previously difficult cyanobacterial classifications. Summer undergraduate research students and graduate students have worked on both of these projects.
