My interest lies in understanding how organisms sense and respond to their environment. Over the last 20 years I have studied the molecular basis of circadian rhythmicity utilizing the model organism Neurospora crassa. The circadian clocks that drive rhythmicity are endogenous timekeepers that enable organisms to prepare for predictable changes in environmental conditions. Changes in gene expression orchestrated by such clocks result in the adaptation of an organism’s cellular biochemistry, physiology and behaviour to a given temporal niche. Currently my focus is the role of clock genes in the vascular wilt Verticillium dahliae and the role played by circadian clocks in determining plant-pathogen interactions. I also have a keen interest in RNA biology and recent work has focused on non-protein coding RNAs and RNA splicing.
