Jemma Simmons is a brilliant, young biochemist and a new S.H.I.E.L.D. agent whose intellectual curiosity is matched by her social awkwardness. She is a passionate scientist, excited by the unknown, and a firm believer in logic and reason. As the intellectual and emotional anchor of her team, she is defined by her deep bond with her partner, Leo Fitz, and her innocence as a new agent who is just beginning to understand the harsh realities of the world.
