Primary research interest

Molecular genetics of gene expression and development

About me

I was a Postdoctoral Fellow and a Research Fellow at ANU, and then a Higher Scientific Officer in The Sainsbury Laboratory, John Innes Centre, Norwich, UK. I was appointed to a senior lectureship at the University of Queensland in 1993, initially in School of Land & Food Sciences, and then relocated my lab to School of Chemistry and Molecular Biosciences in 1997.

Research focus and collaborations

My laboratory focuses on using plants as model genetic organisms. The research theme of my laboratory is the role of RNA interference and epigenetics in regulation of gene expression, and response of genomes to the environment. Genetic and molecular approaches are being used to identify and clone key plant genes involved in gene silencing. We are particularly interested in genes involved in intercellular RNA signaling, and how these affect plant development and plant defence against viruses and transposons. We are also investigating in the role of intron splicing in regulation of gene silencing and gene expression, and the role of epigenetics in pollen development.
