I am mainly interested in understanding the underlying physical mechanisms responsible for the phenomenon of transition to turbulence in fluid dynamics, a long standing open problem of classical physics. In particular, my research focuses on the seek of the so called Exact Coherent Hydrodynamic Structures, that have long been vindicated by theoricists as the precursors and backbone ingredients required to generate and sustain turbulence. My research embraces many branches of applied mathematics, ranging from nonlinear partial differential equations, dynamical systems and bifurcation theory, to highly advanced numerical and computational methodologies, such as spectral Fourier-Chebyshev-Legendre methods, or Newton-Krylov homotopy techniques, to mention just a few.
