The Early Universe is nowadays probed with unprecedented precision by Cosmic Microwave Background (CMB) and Large Scale Structure (LSS) experiments. This poses severe challenges to our comprehension of the physical processes occurred in the Early Universe, as well as the nature of the Dark Cosmological Components. The SISSA Astrophysics group, led by Carlo Baccigalupi, Nicoletta Krachmalnicoff, Davide Poletti, has coordination roles in data analysis, pipeline preparation, data exploitation and interpretation in operating ( PolarBear, Simons Array) and planned experiments (Simons Observatory, CMB-S4, LiteBird). Also, Carlo Baccigalupi coordinates the activities on cross-correlation between CMB and LSS for the forthcoming European Space Agency satellite, Euclid. These activities have three main goals:

◾ Measuring the amplitude of Cosmological Gravitational Waves through the B-modes of CMB polarization

◾ Measuring the behavior of the Dark Energy, responsible for the Cosmic Acceleration, through the Gravitational Lensing effect on CMB and LSS

◾ Exploiting Data Science for designing new algorithms for the analysis at all levels of the data reduction of the quoted experiments.

At this moment, projects will cover the entire next decade at least, and will bring new knowledge in Fundamental Physics, Astrophysics, Cosmology and related fields in Data Science. Here, we listed available and ongoing Master and PhD thesis projects on these matters. Support to these researches is given by the EU H2020 RadioForeground Grant, the ASI-COSMOS network of the Italian Space Agency, the INFN Indark Initiative (all projects), the 2015 PRIN (Euclid).
