Position

Lecturer at the Department of Physics, Astronomy and Mathematics at the University of Hertfordshire and researcher in Mathematical Physics.

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.

Short bio

PhD in Theoretical Physics at the Centre for Research in String Theory (currently known as Centre for Theoretical Physics) at Queen Mary University of London, under the supervision of Prof. David Berman.

MSc in Quantum Fields and Fundamental Forces at Imperial College London under the supervision of Prof. Chris Hull.
