Irina trained as a dancer in Paris, studying with Vera Trefilova and Eugene Lapitsky, and beginning pointe work with her grandmother.
In 1935 she was forced to interrupt her dancing career after suffering injuries in a car accident that killed her brother, Leo.
Following her mother's death in 1972, Irina co-edited and co-translated the first part of Bronislava's autobiography,, Early Memoirs, with Jean Rawlinson.
Irina's staging of "Les Noces" for the Feld Ballet, in 1985, was notable for the design of a new set by Ming Cho Lee.

"Bronislava Nijinska: a Dancer's Legacy," was curated by Nancy Van Norman Baer and first seen at the Cooper-Hewitt Museum in New York, from March to July of 1986, then at the California Palace of the Legion of Honor in San Francisco, from September 1986 to January 1987.
