      The most important discovery for my work is the prism, when Isaac Newton was the first to see how white light splits into different colours in 1666. For my work I look at particular colours of light and I can work out if stars are moving towards or away from us and how fast. (Think the Doppler shift and police sirens.)

      I’m just realising more and more that Hannah & I have such different roles, but so many similarities. The Doppler effect is used in my work as well, to work out the direction of flow of blood in vessels and the velocity of flow, to check if vessels are diseased or not.

      In my work it’s the way to harness different types of energy (sound, x-ray, magnets) to image the human body.

      There are far too many to even know where to begin! All of science?! Everything I do is based on something of what we already understand, so previous discoveries that cells move differently depending on their environment, or discoveries about how to make tiny structures on surfaces. What’s new is how we put those ideas together, to ask new questions.
