Clara Törnvall has been an active culture journalist and producer since the early 2000s. She has produced a number of programs for Swedish Radio and TV as well as written articles and chronicles for dailies and the monthly press. She is a recurring chronelist for Aftonbladet, Svenska Dagbladet as well as the magazine Fokus and has edited several commercial TV-shows and taken part in a number of anthologies. In 2017 her documentary film about the art collector Theodor Ahrenberg, The Art Collector and the Tragedy, debuted on Swedish Television.

At the age of 42 Törnvall underwent an autism examination that diagnosed her with high functioning autism. This led her to write the book The Autists – Women on the Spectrum, that she felt filled a void since the diagnosis is normally portrayed in children and in men but that it looks different for women.
