The sole female Doctor. In 5x02 - Parasomnia, she and the Pathologist hold Tracy Stewart, one of their Chimeras while the Surgeon injects her with a modified needle so to activate her powers.

 

In 5x04 - Condition Terminal, once the Surgeon decides Donovan Donati "looks promising", the Geneticist performs a  procedure on the delinquent, tearing out his normal teeth, so to have Donovan grow new wendigo teeth to accentuate his transformation.
