Experience

  • 1996-97, Visiting Assistant Professor, Mechanical Engineering, IIT Kanpur
  • 1995-96, Research Associate, Aerospace Engineering, IIT Bombay

Research Interests

  • Computational aeroelasticity of wings and turbomachinery.
  • Aerothermoelasticity of hypersonic vehicles.
  • Fluid-elastic interactions in flapping propulsion.
  • Flutter prediction and identification.
  • Molecular mechanism underlying viscoelasticity and damping in polymers.
  • Friction, impact, and vibration induced sound.

Research Statement

I work on problems at the interface of fluid dynamics and elastodynamics of solids. This includes the interplay of vorticity and elastodynamics in flapping propulsion and fluttering flags, transonic flutter in aircraft wings, unsteady flow and flutter in turbomachinery, noise induced due to vibration and impact, and flight flutter identification. We have also investigated the molecular basis of polymer viscoelasticity in terms of the influence of polymer structure on anisotropic stress using molecular dynamic simulations.
