My main research topic is testing and constraining cosmological models alternative to the concordance LCDM cosmology. I work on modified gravity theories, such as brane-worlds or modified actions, as well as scalar-field phenomenological models, e.g. quintessence or k-essence. Amongst the several observables that can be used to this purpose, I focus my research on weak gravitational lensing and, more recently, those probed by other large-scale surveys like wide-field continuum radio surveys.
