Research

I use methods from the nonlinear dynamics in computational studies of emergent complex behavior in physical systems. My current focus is the theoretical aspects of the transition to turbulence in shear flows. The video below is a sample result from my ongoing research.


  • Transition to turbulence in pipe flow captured on the unstable manifold of a traveling wave solution.


  • Left: Motion on the unstable manifold. Right: Flow structures during the transition to turbulence. N. B. Budanur, B. Hof (in preparation). All rights reserved.
