Research and professional activities
Research interests
Imaging specialist (across phyla)
Imaging specialist with a focus on developing methods for quantitative microscopy: Main expertise is low-light, in vivo fluorescence microscopy and quantified image analysis, using different imaging modalities, multi-scale approaches and fluorescent proteins. For biomedical and environmental applications.
Development of genetic probes based on GFP for non-invasive detection and quantification of reactive oxygen species and antioxidants in subcellular compartments
Fluorescent protein biosensors are showing great promise in allowing the real time, spatial and quantitative detection of specific small molecules in living cells. We have engineered and used these biosensors in cells of the leaf to detect hydrogen peroxide, glutathione, lipid peroxides, oxidised ascorbate (vitamin C) and changes in pH. The detection spatially in real time has allowed us to develop a new hypothesis on the spatial dependency of signalling from chloroplasts to the nucleus in leaves exposed to high light - only those chloroplast in contact with the nucleus are capable of triggering a change in gene expression in response to high light. We have provided evidence, using these biosensors, that hydrogen peroxide is the mobile signal that transfers directly to the nucleus from connected chloroplasts. This work has led to further developments in biosensor technology in my laboratory, which in collaboration with colleagues in the School is beginning to extend our detection capability to animals cells and for studying other important signalling molecules.
