    Cathy Yuen Yi Lee has applied her statistical expertise to roles in public health all over the world.

    Although she is now based in Zurich, Switzerland, as a data scientist at Google, Cathy Yuen Yi Lee spent a large chunk of her career as a biostatistician tackling public health challenges.

    “In very simple terms it’s applying statistics to medical and health problems,” says Cathy. “It can really make a difference to public health policy.” This was the case when she analysed risk factors for a NSW State Health Plan around premature babies.

    While she has landed some spectacular jobs, from Harvard University to Google, Cathy says she didn’t start out with a detailed set of goals.
