The research in my laboratory is
centered on understanding the molecular biology of ribosome biogenesis
in eukaryotes. Using molecular genetic and biochemical approaches, we study
several post-transcriptional events in ribosome maturation, including rRNA
processing and ribosomal subunit transport. Our goals are to determine
1) the recognition signals and biochemical machinery involved in the excision
of transcribed spacers from precursor rRNAs, and 2) the specific components,
interactions, and developmentally-regulated pathways involved in transporting
ribosomal subunits across the nuclear envelope into the cytoplasmic compartment.
