She was born in Lithgow, Australia on June 7, 1950, and spent her childhood as well as early adulthood in Sydney. She graduated from the University of Sydney in 1972, earning a Bachelor of Science degree.

Iryna was the beloved daughter of the late Olena and Yaroslav Shewchyk, and daughter-in-law of the late Olena and Peter Kosel.

When she wasn't working as a microbiologist or volunteering to a good cause, Iryna pursued her growing art collection and supported a wide assortment of charities. She was also fervent in the defense of her Ukrainian heritage, often writing letters and comments to the New Yorker and various other publications.

A memorial service will be held in the chapel at the Gate of Heaven Cemetery at 11:00 am on Wednesday, April 29, 2026, in Montgomery, Ohio.
