Research Interests

The research in my laboratory is aimed at:

  • elucidating the molecular machinery responsible for cell division in bacteria and
  • determination of the temporal and spatial regulatory mechanisms necessary to ensure that the septum is placed at midcell and that newborn cells each receive a copy of the chromosome. Our work with the bacterium E. coli has led to the discovery of a cytoskeletel element, the Z ring, that directs septation in all prokaryotic organisms. The Z ring is formed by the self assembly of FtsZ, the ancestral homologue of tubulin.

Our present work involves:

  • characterization of FtsZ assembly in vitro;
  • mechanisms involved in positioning the Z ring at the division site; and
  • determination of assembly pathways for other cell division proteins that are localized to the division site.
