He was previously Chair in Applied and Numerical Analysis at the Department of Mathematics, Imperial College London, United Kingdom, a position he held from October 2012 till March 2020.

[6] In 2018, he was elected to the European Academy of Sciences,[7] and nominated Changjiang Visiting Scholar (2018-2021) by the Ministry of Education of the People's Republic of China.

He has made contributions to the understanding of the asymptotic and qualitative behavior of solutions to nonlinear diffusion equations, particularly through the use of entropy methods and gradient flow techniques.

[12] He has also worked on kinetic and diffusive models in mathematical biology describing chemotaxis, flocking and swarming behavior of interacting agents, as well as on computational neuroscience.

He participated in the Committee of Science Policy and is member of the Scientific Advisory Board of the Sociedad de Científicos Españoles en el Reino Unido (Spanish Society of Researchers in the UK) SRUK/CERU.
