Jennifer Keller

Dr. Jennifer Keller is a fictional character from the Canadian-American military science fiction series ''Stargate Atlantis'', a spin-off series to ''Stargate SG-1''. She is played by Canadian actress Jewel Staite, who previously played the Wraith Ellia in season two episode "Instinct". She was created by the producers, who wanted someone to fill in for Carson Beckett after Paul McGillion's departure from regular status in the series. Keller had a recurring role in the fourth season, and was later promoted to a regular in Season 5.

Dr. Keller was introduced in the third season finale, "First Strike". She is a brilliant young doctor and becomes a member of the Atlantis Expedition, and has taken charge as Atlantis' Chief Medical Officer, after the death of Dr. Carson Beckett. At first, she appears as a non-assertive character, but has proven to be courageous over time. Towards the end of the fifth season, she starts a relationship with fellow expedition member Rodney McKay. In 2008, Staite was nominated for a Gemini Award in "Best Performance by an Actress in a Continuing Leading Dramatic Role" for her role as Keller, and in 2009, she was also nominated for a Leo Award in "Best Lead Performance by a Female in a Dramatic Series."
