Postdoc researcher in Mathematical Physics at the University of Hertfordshire. PhD candidate in Theoretical Physics at the Centre for Research in String Theory (currently known as Centre for Research in Theoretical Physics) 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.
On global double field theory formulated in higher differential geometry:

(relating Kaluza-Klein compactification on principal ∞-bundles to double field theory, T-folds, non-abelian T-duality, type II geometry, exceptional geometry, …)
