Research Interests

• One project is currently focused on the regulation of stress-inducible genes in cyanobacteria. We have identified genes and gene products inducible under nutrient (Fe) limitation and oxidative stress conditions.
• A second project is concerned with examining the protein/protein interactions necessary to mediate the docking of plastocyanin to its reaction partners cyt f and PSI.
