Jocelyn Kilroy is the Executive Director of the Contagion Research Center.
In "Sacrifice", after the League of Assassins broke into the center and released a vial of Calibosix toxin, Kilroy approached Lieutenant Gordon with approval from the Mayor's office to initiate breach protocol. Gordon did not believe the situation had escalated that far yet. Kilroy only wanted to protect public safety from an epidemic and didn't think Batman's life was worth waiting on. Gordon managed to convince the Mayor to rescind her approval but Kilroy retaliated by gaining the Governor's authorization.
"Epitaph" revealed that Kilroy was running for mayor against Harvey Dent and David Hull. Dent makes some sexist remarks about her during a rally.
In "Twist", Kilroy runs negative campaign ads against Dent, focusing on his failures against Batman. The district attorney, now disfigured and criminally insane, threatens her with Anarky's help and forces her to resign the mayoral race.
