(written from a Production point of view)
Mathilde "Tig" O'Callaghan Notaro (born 24 March 1971; age 49) is an American stand-up comic, writer, radio contributor, and actress. In Star Trek: Discovery she plays Jett Reno, former chief engineer of the USS Hiawatha who transfers to the USS Discovery.
After her stand-up show Live, in which she announced she had cancer, brought her widespread acclaim, she became the subject of the Netflix documentary Tig. After she was diagnosed with life threatening C. Diff as well as bilateral Breast Cancer, and her mother dying all within a short space of time, the documentary deals with her recovery and her attempts to have children, as well as her burgeoning relationship with (her now wife) Stephanie Allynne, and return to stand-up comedy on the annivesary of such a ground breaking show. Other stand-up shows include Boyish Girl Interrupted, and Happy To Be here, and in 2014 she performed topless, baring her mastectomy scars, at the New York comedy festival.
Notaro and Allyne have been married since 2015, and co-starred in and co-wrote the Amazon Prime sitcom One Mississippi, which ran for two seasons until 2017. Notaro has also appeared on Transparent, Fresh Off the Boat, Garfunkel and Oates, The Jim Gaffigan Show, The Office, and Community, starring Danny Pudi and Gillian Jacobs (in an episode where her friend Paul F. Tompkins also featured). She reunited with Jacobs in the 2014 film Walk of Shame.
