Research Interests

• The study of the developmental cycle of the bacterium, Bdellovibrio bacteriovorus. The bdellovibrios are obligate preditors of other Gram-negative bacteria, exhibiting a byphasic life cycle characterized by a free living attack phase and an intraperiplasmic growth phase..
• Ongoing projects include:
  1. The development of a physical map of the Bdellovibrio genome.
  2. A study of the receptor for Bdellovibrio attachment to its prey cell.
  3. Characterization of conditional mutants in the developmental cycle of the bdellovibrios.
  4. A study of the taxonomy of the bdellovibrios using random amplified polymorphic DNA analysis (RAPD).
