DESCRIPTION:Consistency with quantum gravity can have non-trivial implicat
 ions at low energies. The Swampland program aims to determine the constrai
 nts that any EFT should satisfy to be consistent with a UV quantum gravity
  completion. In this talk\, I will revisit the most important Swampland co
 njectures that can have implications for Cosmology\, especially for inflat
 ionary models. In particular\, the Swampland Distance Conjecture (SDC) res
 tricts the geodesic distances that scalars can traverse in EFTs as they ap
 proach points at infinite distance in moduli space. We propose that\, when
  applied to the subset of light fields in effective theories with scalar p
 otentials\, the SDC restricts the amount of non-geodesicity allowed for tr
 ajectories along valleys of the potential. This is necessary to ensure con
 sistency of the SDC as a valid swampland criterion at any energy scale acr
 oss the RG flow\, and it constrains the inflationary potentials consistent
  with quantum gravity. I will then compare these bounds with the asymptoti
 c form of the scalar potential of flux string compactifications. Our resul
 ts suggest that these compactifications lead to the most generic potential
 s allowing for maximum non-geodesicity of the potential valleys while resp
 ecting the SDC along them. These potentials also preserve an asymptotic ve
 rsion of the de Sitter conjecture\, which provides a lower bound on the sl
 ope of the potential.
