About Me

Relaxed, Australian surfer

As well as doing science I love to surf (see photos) and travel. I have been lucky enough to surf all around the world, including Bali (Indonesia), Australia (where I am from) and the Philippines.

At the end of my PhD (science degree), I hope I am better at science than I am at surfing!

I currently live in Oxford and as well as working as a scientists I work as an emergency doctor at the Oxford University Hospital.

My Work

We try and identify medical tests and treatments that don’t work.

At the moment, we know doctors order some tests and treatments that don’t work. This is a worry because it can cause side effects for patients, even when though the tests and treatments don’t work.

We hope we can identify these tests and treatments so patients, like you and I, don’t have to have blood tests or x-rays that they don’t need too!

My Typical Day

Some days I go to the hospital and work as a doctor in the emergency department. Other days I go to Oxford University and do science!

What I'd do with the money

I would create a scholarship to allow an Indigenous Australia to study at Oxford.
