Research Interests

We are constructing a plasmid vector that will allow insertion of any gene of interest at a defined site on the Bacillus anthracis chromosome. We are characterizing a new class of B. cereus/anthracis phages that may be used for bio-control.

Current Projects

We are constructing an integration vector--a plasmid that can insert in the B. anthracis chromosome--that will allow us to express particular antigens of B. anthracis at a high level. The new phages that we are characterizing are extremely virulent. We intend to determine why this is so.
