I'm a Reader in Applied Mathematics at Imperial College. My interests are in mathematical modelling, asymptotic analysis and singular perturbation techniques, usually applied to problems involving fluid dynamics, transport phenomena and waves. 

I can offer PhD projects in the research areas mentioned above. Please contact me for more details.
