A scientist, who worked for the Klingon-Cardassian Alliance, Jennifer was working on a sensor system which would enable the Alliance to scan the Badlands in detail and so hunt down and destroy the Terran rebels once and for all. Fortunately our own version of Ben Sisko was able to reach Jennifer and convince her to change sides.

The plan worked, though Jennifer was murdered by the mirror Kira Nerys during the battle. [3]
