Clinical interests in breast cancer, gastrointestinal cancers, and haematology.

Yvonne completed her general medical training in Western Australia before moving east to the Peter MacCallum Cancer Institute in Victoria to complete her training in radiation oncology.

The offer of a fellowship in breast cancer at Westmead Hospital saw her move to Sydney, and this was followed by a position as a consultant radiation oncologist at the Prince of Wales Hospital in Randwick.

In 1999, Yvonne moved to Boston for a clinical fellowship at the Massachusetts General Hospital. On her return to Perth, she began working as a consultant radiation oncologist and joined GenesisCare in 2011.
