Not sure when she left, but she posted today that she started a new job at Bungie.
She did a lot of open world and raid content, including Tequatl Rising (the Teq redesign), Triple Trouble Wurm, the Chak Gerent fight, and was (iirc) the lead designer for raids up until Wing 5.
Wishing the best of luck to her in her new role!
