Current Research

My lab's research is focused on sensory system development in Drosophila melanogaster . We study the mechanisms by which different cell fates are partitioned during development and how each cell type differentiates to help produce a functional organ for the peripheral nervous system. Currently, work in the lab involves an investigation of the function of the transcription factor D-Pax2, a protein expressed in both photosensory and mechanosensory organs in Drosophila . The mammalian homologs of this protein are central to the proper development of eyes and ears. Projects include the identification of transcriptional targets of D-Pax2 in different tissues and an examination of the regulation of D-Pax2 expression during sensory organ development.
