Abstract: (submitter)

This thesis contributes to studying primordial cosmology theories and their detectability in future observations. The first part of the thesis studies a class of inflation models with curved field spaces, which are typically motivated in high energy physics theories. The second part of the thesis focuses on one particularly important cosmological observable -- primordial non-Gaussianity, whose phenomenology may reveal new physics effects in the very early Universe.
