Abstract
The problem of moduli stabilisation is discussed in type IIB/F-theory. Considering a configuration of three intersecting D7 branes with fluxes, it is shown that higher loop effects induce logarithmic corrections to the Kaehler potential which can stabilise Kaehler moduli, in particular the internal volume of the compactification space in 4 dimensions. It is also explained how D-term contributions to the effective potential stabilise the rest of the Kaehler moduli and uplift to de Sitter vacua.
