Research Interests

I am primarily interested in experimental studies of hydrodynamic stability and bifurcation phenomena in fluid systems. Currently I am investigating transition to turbulence in pipe flow. Previous studies were concerned with MHD convection in liquid gallium and multiplicity of states in Rayleigh Bénard convection.
