My research focuses on matter couplings to N=2 supergravity. I am concentrating on instanton corrections to hypermultiplet moduli spaces in CY compactifications of Type IIA strings, motivated among others by the fact that in combination with fluxes such quantum effects can fix the moduli in meta-stable de Sitter vacua.
