N2 - Infinite derivative theory of gravity is a modification to the general theoryof relativity. Such modification maintains the massless graviton as the onlytrue physical degree of freedom and avoids ghosts. Moreover, this class ofmodified gravity can address classical singularities.In this thesis some essential aspects of an infinite derivative theory ofgravity are studied. Namely, we considered the Hamiltonian formalism, wherethe true physical degrees of freedom for infinite derivative scalar modelsand infinite derivative gravity are obtained. Furthermore, the Gibbons-Hawking-Yorkboundary term for the infinite derivative theory of gravity was obtained.Finally, we considered the thermodynamical aspects of the infinite derivativetheory of gravity over different backgrounds. Throughout the thesis, ourmethodology is applied to general relativity, Gauss-Bonnet and f(R) theoriesof gravity as a check and validation.
