nLab Luigi Alfonsi




Postdoc researcher in Mathematical Physics at the University of Hertfordshire.


My main research interest lies in the global geometric structures underlying the dualities of string theory and M-theory, to join the dots between double field theory, gerbes, generalized geometry, non-geometry and T-folds.
