  Recent and upcoming experimental data as well as the possibility of rich
phenomenology has spiked interest in studying the quantum gravitational effects
in cosmology at low (inflation-era) energy scales. While Planck scale physics
is under development, it is still possible to incorporate quantum gravity
effects at relatively low energies using quantum field theory in curved
spacetime, which serves as a low-energy limit of planck scale physics. We use
the Vilkovisky-DeWitt's covariant effective action formalism to study quantum
gravitational corrections to a recently proposed Natural Inflation model with
periodic nonminimal coupling. We present the 1-loop effective action for this
theory valid in the flat-potential region, considering perturbative corrections
upto quadratic order in background scalar fields.
