Research interests: 

• Viscoelasticity-induced instability in shear flow (drag reduction, elasto-inertia turbulence, elastic turbulence)

• Pattern formation and sustaining of turbulent-laminar transitional structure (turbulent puff/stripe, bifurcation theory,  chaos)

• Transition to turbulence in 3-dimensional boundary layer (free-stream turbulence,  cross-flow instability, receptivity)
