The PhD thesis will consist in investigating the chemical evolution of galaxies across the cosmic epochs and, from this, constrain the role of different mechanisms and physical processes (e.g. galactic outflows, gas accretion, star formation efficiency) in galaxy formation and evolution. The thesis work will involve the analysis of data from current and forthcoming facilities (e.g. SDSS, JWST and MOONS) and also the development of models for the data interpretation, including the comparison with the prediction of cosmological numerical simulations.

博士论文将包括在整个宇宙时代的星系的化学演化的调查，并从这一点，限制不同的机制和物理过程（如星系外流，气体吸积，星星形成效率）在星系形成和演化的作用。论文的工作将涉及从当前和即将到来的设施（如SDSS，JWST和MOONS）的数据分析，也为数据解释模型的发展，包括与宇宙学数值模拟预测的比较。
