Research Interests:

Our work is currently focused on the regulation of nutrient-stress-inducible genes in cyanobacteria. We have identified genes and gene products inducible under nutrient (N, S, P) limitation and stationary phase conditions, and this work has aided in the development of whole-cell biosensors detecting the bioavailability of nutrients in environmental samples. Secondly, we examine the composition and dynamics of cyanobacterial communities in aquatic systems. Third, we are examining the structural requirements for productive electron transport in photosynthesis by studying the protein-protein interactions occurring between the copper protein plastocyanin and its reaction partners (Photosystem I and cytochrome f).
