I will discuss two types of singularities in amplitudes caused by null geodesics in anti-de Sitter spacetime and their resolutions by stringy effects. Certain Landau singularities are resolved by the Gross-Mende effect, and null singularities near the black hole photon sphere are resolved by stringy tidal effects. Interpretations of these singularities and their resolutions in the context of...

I will report on progress in computing four-dimensional effective theories of quantum gravity from compactifications of string theory. I will describe applications to axion cosmology, the strong CP problem, and black hole superradiance, emphasizing novel aspects that arise when the number of moduli is large.
