Tell us a bit about your research?

What I work on is cells. We're all made of billions of cells. I work on the process called the cell cycle by which a cell reproduces itself from one to two. That requires a series of events: Events that particularly lead to the doubling of the DNA and the segregation/separation into two newly divided cells.

What controls that overall process, what goes through all those events in the right order, and the impact that led to the Nobel Prize was the discovery that it's a very simple system: There's a particular enzyme called cyclin-dependent kinases, which increases as you go through the cycle and fires off different events at different levels. And then when it gets to the end of the cycle, it's destroyed and then it goes through it again.

Why do you think cancer incidence is rising so sharply globally?
