Nico Gray is Professor of Applied Mathematics and Deputy Director of the Manchester Centre for Nonlinear Dynamics a joint Institute formed by the School of Mathematics and the School of Physics & Astronomy to study nonlinear phenomena through a combined approach of theory, numerical computation and laboratory experiment.

He graduated with a first class degree in Mathematics from The University of Manchester in 1988 and was awarded a PhD on sea-ice dynamics by Cambridge University in 1992. He also holds a Habilitation in Continuum Mechanics and Geophysical Mechanics from the the Technical University of Darmstadt, Germany.

Following postdoctoral research positions at the School of Mathematics, University of East Anglia and the Institute of Mechanics, Technical University of Darmstadt he was appointed to a Lectureship in Mathematics at Manchester in 1998. He was subsequently promoted to Senior Lecturer (2003), Reader (2004) and to a personal chair in 2006.

In 2003 Nico was one of the main international organizers of a four month research programme on Granular and Particle-Laden Flows at the Isaac Newton Institute in Cambridge. From 2004-2009 he held an EPSRC Advanced Research Fellowship on particle size segregation, mixing and pattern formation in rapid granular avalanches. He currently holds an  EPSRC Established Career Fellowship on particle-size segregation in chutes, silos, conveyor belts and rotating drums, a Royal Society Wolfson Research Merit Award and a  NERC grant on self-organization and run-out behaviour of geophysical mass flows.
