I work as an intensive care doctor. I look after very sick patients that need machines to stay alive. Since doing research into infection, I have been caring for people with sepsis when their body's response to germs gets out of control. I hope that science can help find ways to help them better survive.

When I was at school, I told the career’s adviser that I wanted to be an FBI agent. Now, though, I say every day in my job I use science, encounter questions for which there are no answers, and my most valuable tool are the people I work with.

So it doesn’t feel that different from being a spy.

It’s not always possible to save patients in intensive care, and that is very hard. But death is a part of life, and we have to be excellent at that aspect of care too. I take a lot of solace in making that part of a person’s life as good as it possibly can be.
