My research programme focuses on developmental genetics, using Arabidopsis thaliana as a model system. Forward and reverse genetic screens are employed to identify genes that act to control the partitioning of stem cells into new organ primordia. A battery of genetic, biochemical, cytological and genomics techniques are used to elucidate the function of these genes and to illuminate how their encoded proteins contribute to the genetic network that underpins development and stem cell biology.
