Research

I am working with Lynette Brownfield on identifying processes that are involved in male gamete (pollen) development. In particular, I will be looking at how gametes form which have not had their ploidy level reduced during meiosis and thus are termed unreduced. I will be using mainly molecular-genetic approaches such as mutants in the model plants Arabidopsis thaliana and Medicago truncatula in order to characterize the underlying mechanisms and how a protein called JASON impacts the cytoplasmic organization during male meiosis.
