My research interests lie in the field of string phenomenology, which connects the UV complete framework provided by Superstring theory to field theoretical models such as the Standard Model of particle physics and cosmology. The connection is established using “string effective actions”, given by certain supergravity theories. Especially beneficial is the approach over F-theory, which is best accessed through eleven-dimensional supergravity and allows to deduce 4d, N=1 supergravity theories that exhibit chiral spectra and exceptional gauge groups relevant for Grand Unified Theories. My current focus is on string theory induced α’, gs and Kaluza-Klein corrections to these supergravity theories. The study of the modified dynamics of these effective theories, especially the determination of their vacuum structure, is of crucial phenomenological importance and also of significant conceptual interest.
