Research interests

My research interests span both the early- and late-time Universe. Over the years, my primary focus has been on developing mathematical techniques to investigate cosmological perturbation theory at non-linear regimes specifically adapted to a past light-cone description. These mathematical formalisms may be applied to the study of gauge invariant relativistic corrections to cosmological observables, the study of backreaction effects, description of primordial gravitational waves, among other perturbative effects. Recently, I have also become interested in exploring scalar-tensor theories of gravity for the purpose of model building in Inflationary and Dark Energy scenarios.
