At Cambridge, there was a completely unintimidating culture, and there were no class divisions among the students.

In my early work, our molecular views of telomeres were first focused on the DNA.

No one ever said, 'Be a doctor.' But because so many members of my extended family - aunts, uncles - were doctors, there was this expectation that I'd probably be a physician.

They have to look at what individual students have done rather than at their class rank because everybody that applies to them is in the top of their class.

I think most students come in knowing what to expect. They've heard about the class and about me.

Long assignments that take longer for me to do than the other students in my class to do.
