Luigi Alfonsi



PhD student in theoretical physics at the Centre for Research in String Theory at Queen Mary University of London, under the supervision of prof. David Berman.


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.
