Jemma Simmons

Jemma Simmons is a British born S.H.I.E.L.D. agent and scientist. A genius biochemist, she is one of the youngest and most prominent members of S.H.I.E.L.D.’s research division, along with her equally brilliant partner, Leo Fitz.

She, along with Fitz were recruited to Coulson's Team by Melinda May and worked with them on all of their missions. Simmons was an active participant in hunting for John Garrett and the rest of the Centipede Project. She was shocked and saddened to learn that Agent Ward had been a member of HYDRA all along, and became bitter towards him resulting in several arguments with Fitz. Despite the events surrounding the Battle at Cybertek and Fitz's severe injury, Simmons stayed with the team to help rebuild S.H.I.E.L.D. as Nick Fury requested.
