Current PhD students

Students co-advised informally at Imperial College London:

Mr. Rajagopal Vellingiri -  Thin film flows and droplet dynamics (co-advised with Prof. Serafim  Kalliadasis)

Research interests

  • Complex flows: wetting phenomena; investigation of free-surface flows supported on substrates influenced by substrate morphology (chemical and topographical), vibrations or other effects, such as the presence of a turbulent gas; dynamics of curved, unsupported liquid films; liquid jets.
  • Applied mathematical modelling: singular perturbation methods and matched asymptotics; dynamical systems and bifurcation analysis; stochastic processes; physical resolution of singularities in mathematical models.
  • Numerical methods: accurate and efficient numerical schemes for nonlinear PDEs via spectrally accurate methods; improved numerical schemes for dynamic density functional theory; numerical continuation.
  • Statistical mechanics of inhomogeneous fluids: analytical approaches to density functional theory; extensions to far-from-equilibrium dynamics; formalism.
