Toronto's Hospital for Sick Children has a new summer researcher who used to be a patient.

When Ben Diplock was eight years old, he was diagnosed with a brain tumour.

Between surgery and various follow-ups, Diplock spent a decade in and out of the hospital.

He will soon graduate from McMaster University with a science degree.
