Born in Copenhagen, Denmark, Sandi’s formative years were spent around the USA, Africa and Europe. 

At Cambridge University she discovered a flair for comedy where she wrote and performed in the first all-female show for The Footlights. Graduating with a First Class Honours Degree, she is now known and loved by millions as one of our most accomplished writers, presenters and comedians.

Having begun her TV career playing Ethel in the Saturday series Number 73, Sandi has become a regular face on the small screen where she has been a team captain on Call My Bluff and Whose Line Is It Anyway, hosted Antiques Master for BBC 2 and on 1001 Things You Should Know for Channel 4. Other presenting credits include; Fifteen to One, The Great British Bake Off and the hugely popular QI where she took over as host from Stephen Fry.

On radio, Sandi has chaired The News Quiz for over a decade which led to her induction into the Radio Hall of Fame.

Passionate about live performance, she appeared at the opening night of London’s Comedy Store and enjoyed a long spell as a member of The Comedy Store Players. She also founded Playhouse Live for Sky Arts where her roles included both writing and acting as Executive Producer.

A prolific writer, Sandi has had more than 20 fiction and non-fiction books published including her long awaited memoir Between the stops: A View of My Life from the Top of the Number 12 Bus, co-authored Big Nighty Out, The Shakespeare Deconstruction:The Pocket Dream, Charity Begins and adapted Treasure Island which was staged for the re-opening of Leicester Haymarket in 2018.

Other triumphs include her adaptation of Mama Mia:The Party at The 02 and the new family show, Snow Globe at London’s Globe Theatre with Jennifer Toksvig.
