The Fields Medal 2018 awarded to Alessio Figalli, Visiting Professor in the Department of Mathematical Sciences at Durham
The Fields Medal is the world's most prestigious prize for mathematicians. It is awarded by the International Mathematical Union (IMU) once every four years, to up to four recipients under the age of 40. The selection is based both on major early-career contributions and on the promise of future achievements. Mathematicians usually receive this award for solving an outstanding open problem or for developing powerful new methods for gaining novel insights into existing areas of mathematical research. The Fields Medal is often said to be the equivalent of the Nobel Prize for Mathematicians (although there is no age limit for receiving the Nobel Prize).
Kostas Gourgouliatos' simulations explain magnetic hotspots
Knots that form in the magnetic field lines of neutron stars early in their lifetime can be at the origin of magnetic hotspots that persist for millions of years. Together with Rainer Hollerbach, a colleague from Leeds University, Kostas used numerical simulations to model the evolution of the magnetic field.
