She just appeared on Thursday's episode, "Cold Blooded". She was pretty much a detective in the B-plot of this episode (involving missing women), as the A-plot involved robot dinosaurs used in a murder.
Reportedly she's going to be a sort of semi-regular. There's some buzz about her possibly replacing Helgenberger as the second lead of the show (As newcomer Fishburne quickly replaced William Peterson/Grissom). However the show has attempted to introduce new female characters with limited success such as Louise Lombard and Lauren Lee Smith's characters who didn't stay for very long (And were mainly replacements for Sara, who is now back on the show again).
