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.

Research

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.

Selected writings

On global double field theory formulated in higher differential geometry:

Review:

  • Luigi Alfonsi, Towards an extended/higher correspondence – Generalised geometry, bundle gerbes and global Double Field Theory (arXiv:2102.10970)

On the geometric quantization of a sigma-model in double field theory:

On other global geometric aspects of theoretical physics (e.g. classical double copy):
