Research Interest

Plants are sessile; as such the ability of a plant to sense and respond to its changing environment is essential for its survival.  Plants are able to coordinate growth in response to very specific stimuli.  For example, a compound that occurs in smoke, called karrikin, promotes seed germination and developmental changes in Arabidopsis as well as several other species.  My current research aims to understand the molecular mechanisms by which Arabidopsis responds to the presence of karrikin.  To identify genes with important roles in coordinating growth responses to karrikin, I use both forward genetics – the process of beginning with a heritable phenotype and working to identify the causative genetic locus; and reverse genetics – the process of studying genes of interest in an attempt to connect them to a physiological process.  Forward and reverse genetic techniques are not exclusive to plant biology, but may be used on a wide range of organisms.
