I give an overview of a research program that aims to formulate the target space description of string/M-theory in a way that is manifestly covariant under the duality symmetries that conventionally are only visible for special compactifications. Such theories, referred to as double and exceptional field theory, are defined on an extended generalized spacetime. I outline three major research projects where these frameworks seem very promising: 1) Determining or constraining the higher-derivative alpha' corrections of string theory; 2) formulating extended versions of "stringy" gravity that include higher massive string modes; 3) investigating possible applications in the cosmology of the early universe.
