Michelle Winn is the staff development and personnel coordinator for both Corona Tower's aboveground facilities and basement research center.

Underground, she specifically handles non-hybrid support personnel hiring and training. People like Devon Maye, Joseph Howard, and Rachel Prager all went through the hiring process with Ms. Winn, and she is the one that schedules training sessions to keep them current in their fields. 

We first meet Michelle Winn in Book 8 of The Human-Hybrid Project, Sunchaser's Gambit.
