Research

Five questions, one molecule at a time

We design proteins that recognise one short stretch of DNA, measure how well they work, and follow what happens in cells, tissue and plates of ninety-six.

Projects

Six projects, one question each

Every project page lists the methods, the people and the measurements behind it.

Proteins with a built-in clock

Proteins with a built-in clock

Designs that the cell clears on a schedule, so an experiment can have a defined start and end.

Reading eighteen letters of DNA

Reading eighteen letters of DNA

A designed protein that recognises one eighteen-letter stretch of DNA, and the measurements that show how tightly it holds.

A cryo-EM atlas of proteins on nucleosomes

A cryo-EM atlas of proteins on nucleosomes

Fourteen structures showing how designed proteins meet packaged DNA, and why the angle of approach matters.
