I will present recent advancements in stellar populations models tailored for detailed spectroscopic analyses, expanding their applicability beyond the optical to include the NIR and UV spectral ranges. These developments feature innovative treatments of varying abundance ratios, utilizing fully empirical stellar spectra and differential corrections from theoretical models. By enhancing the models' predictive capabilities, these improvements offer powerful new diagnostic tools for interpreting the wealth of data from upcoming
observational programs. Furthermore, I will show how these advancements provide unprecedented constraints on galaxy formation and evolution, made possible by the expanded spectral coverage.

Dr. Alexandre Vazdekis obtained his Ph.D from University of La Laguna in 1996, and then did postdocs in Durham University and University of Tokyo. He is an expert in the formation and evolution of galaxies, particularly the stellar populations of elliptical and lenticular galaxies. He has published 166 papers in peer-review journals with more than 13000 citations. According to Stanford ranking, he is ranked among the top 2% most influential scientists worldwide.
