As a graduate student and postdoc, my research interests focused on understanding the genetic and molecular mechanisms required for development of the oocyte and egg. Prior to joining the Extavour lab, I studied follicle cell patterning in Drosophila and establishment of oocyte polarity in zebrafish. Recently, I have become interested in understanding the mechanisms by which the germline is specified, in particular within an evolutionary biology context. My current project focuses on germline development in the crustacean Parhyale hawaiensis.
