I'm a Senior Lecturer in Applied Mathematics at Imperial College. My research is based on developing and applying asymptotic methods to study contemporary problems in applied physics and engineering. My current work spans a broad spectrum of scientific interests including wave diffraction in micro-structured media, nanophotonics and surface-plasmon resonances of metallic nanoparticles, and several topics in microhydrodynamics (drops in electric fields, slip over superhydrophobic surfaces, and swimming micro-particles and their dispersion under geometric confinement). In the past I also worked on the electrokinetic theory of charged microparticles in electrolyte liquids, conductivity of ion-selective nano-channels, colloidal interactions, and nonlinear magnetic diffusion in metallic conductors.

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