Our lab has a general interest in genetic and epigenetic mechanisms governing seed development and plant speciation. Our main interest focuses on the endosperm, the tissue that supports embryo growth and is functionally analogous to the placenta in mammals. The endosperm is a major source for our daily calories; one of many other reasons to study endosperm development. We decipher the role of the endosperm in controlling seed growth, regulating embryo development, as well as establishing barriers towards interspecies and interploidy hybridizations. Our main model is Arabidopsis thaliana, but we work as well on close relatives like Capsella rubella and Capsella grandiflora. While our main focus is on basic research questions, we also strive to translate our research into practical applications.
