Profile
I am a Mathematician working in the area of Partial Differential Equations and Mathematical Analysis. I am a Reader in the School of Mathematics at Queen Mary University of London and a Visiting Professor in the School of Mathematical Sciences at Loughborough University. Previously I have been a Junior Research Fellow at Imperial College London.
My research interests are:
- Hyperbolic equations and systems with multiplicities
- PDEs with singular coefficients and very weak solutions
- Sub-elliptic problems on compact Lie groups
- Microlocal analysis, Fourier integral operators and pseudo-differential operators
- Algebras of generalised functions
EPSRC support for my research:
EP/L026422/1: Hyperbolic systems with multiplicities (2014-2017)
EP/V005529/1: Hyperbolic problems with discontinuous coefficients (2021-2025)
