Understanding Photosynthesis at the Molecular Level (co-supervisor Dr. Robin Purchase)

Photosynthesis is the process that sustains almost all life on Earth, yet many of its most fundamental molecular mechanisms remain unresolved. Recent discoveries have revealed an unexpected diversity of photosynthetic systems, allowing organisms to thrive across virtually the entire biosphere. How do these systems capture light, split water, and convert solar energy into the chemistry of life?

Using some of Australia's most advanced spectroscopic facilities, students will investigate the structure and function of photosynthetic proteins and pigments. Experimental techniques include low-temperature optical spectroscopy (down to 2 K), magnetic circular dichroism (MCD), high-field Electron Paramagnetic Resonance (EPR) spectroscopy, and double-resonance methods capable of detecting NMR interactions in paramagnetic systems. Projects may focus on biological water splitting, light harvesting, electron transfer, or the remarkable adaptations that enable photosynthesis in extreme environments.
