Photosynthesis uses light energy to synthesize biomass from inorganic precursors, while releasing oxygen. Thus, photosynthesis created and sustains our breathable atmosphere, the food we eat and the environment we need. Human activities are now rapidly increasing atmospheric CO2, UVB radiation reaching the Earth and nitrogen nutrients.
We use molar quantitations of key protein complexes, in parallel with optical measurements, to understand photosynthesis in cyanobacteria and phytoplankton under changing conditions. We also analyze seasonal acclimation in Spartina marsh grass, lichens and conifers.
To support our research on the molecular bases of environmental processes, we collaborate with Environmental Proteomics and AgriSera to develop systems for molar quantitation of major protein complexes across the diversity of photosynthetic organisms.
We are based at Mount Allison University, on the Bay of Fundy and in the midst of the Tantramar Marshes in New Brunswick. We are well equipped for field sampling, controlled culture experiments, photosynthetic physiology and molecular quantitations of proteins, transcripts and pigments. The group usually comprises 1–2 post-doctoral fellows, 2–3 graduate students (some co-supervised through UQAR or the UNB Centre for Ecological and Molecular Algal Research), 2–4 honours students and a technician. We regularly host collaborators from other groups. Students and post-doctoral researchers interested in molecular analyses of ecophysiological processes are welcome to contact dcampbell@mta.ca.
