Born in Neuilly-sur-Seine, Tatischeff was the daughter of Jacques Tati. She began her career as assistant editor on her father's 1967 film Play Time. She also edited both Trafic (1971) and Parade (1974).
After Tati's death, she produced a color version of his 1949 feature Jour de fête using previously unusable color film elements shot simultaneously with the monochrome stock. In 2001, she also re-constructed his 1978 short film Forza Bastia.
Tatischeff died in Paris from lung cancer in 2001.
