David Donoho.

If you have ever been in an MRI scanner you'll appreciate the work that Donoho is being honoured for with the Carl Friedrich Gauss Prize at the International Congress of Mathematicians 2018. His research has revolutionised this imaging technique, leading to significant shortening of the time patients have to spent in the claustrophobia inducing tube. In this video he talks to us about sparse signals, wavelets and an area of signal processing called *compressed sensing*.
