Dr Johanna Turnbull

I am a plant ecophysiologist conducting research in stress biology, photosynthesis, and plant response to climate change including ozone depletion. I am interested in understanding the mechanisms behind plant tolerance to extreme environmental stress focusing particularly on the damaging components of solar radiation and how this is impacted by other abiotic stressors. I have been involved in long term monitoring of Antarctic mosses at Casey station (State of the Environment Indicator 72) since its inception in 2000. I have used Enzyme Linked Immunosorbent Assays (ELISAs), High Performance Liquid Chromatography, spectrophotometric assays, microscopy and chlorophyll fluorescence to monitor health and stress markers in plants. I have completed five field seasons in East Antarctica to explore the strategies plants utilise to survive in this extreme environment.
