The evolution of chemical abundances in galaxies provides crucial information to study how they formed and evolved. Results in the Local Universe show that on average, star-forming gas-phase in galaxies have negative metallicity gradients and that flat and inverted positive gradients could be associated with galaxy interactions and gas accretion. As a function of redshift, there seems to be an increase of the fraction of inverted metallicity gradients. In this talk I will summarize our latest finding on the evolution of the metallicity gradients as a function of stellar mass, galaxy size and star formation efficiency up to z~2.5 in the EAGLE project. I will also show first results on a study of the processes that shape metallicity gradients with the CIELO simulations.
