Title: The evolution of metallicity gradients

Abstrsct: The evolution of chemical abundances in galaxies provides crucial information to study how galaxies formed and evolved.

In particular, metallicity gradients have been largely studied in the Local Universe with important contributions from surveys such as CALIFA and MaNGA.

Observations at high redshift are also providing important clues which could be used to set constraints on the processes that regulate the sfar formation activity in galaxies by using the chemical properties.

I will present results of the analysis of the oxygen abundance gradients in star-forming regions in the disc components of simulated galaxies identified from the EAGLE simulations.

Results on the evolution of the metallicity gradients up to z~3 will be presented. I will also summarize our current on-going projects.
