Research interests
I am a Research Fellow working with Michael Djordjevic on flavonoid signalling in plants and its control on plant architecture. I am also involved in chemical genetics assays to determine mutants resistant to these compounds.
We recently discovered that flavonoids act as long-distance development signals and modulators of plant architecture. To determine if flavonoids have roles in controlling plant development and architecture, we examined a range of flavonoid-pathway mutants in Arabidopsis for developmental aberrations. These mutants revealed a wide variety of architectural phenotypes in root and aerial tissues. Our research focus is to determine the signalling pathways involved.
My overarching interests are in cell biology using microscopy and fluorescence. I also have considerable experience with laser tweezers and microsurgery techniques.
