Interests
My main research interest is in nonlinear dynamics applied to fluid mechanics. I use concepts from dynamical systems together
with machine learning technique to try to improve our understanding of subcritical transition between the laminar and turbulent flow states, as well as taming turbulence.
I work on both Newtonian and complex fluids. I am particularly interested in the transition to turbulence in viscoelastic fluids, where the flow can become chaotic even at low Reynolds numbers, and
many exciting phenomena can be observed (ET and EIT).
To study the emergent complex dynamics we perform large-scale direct numerical simulations using pseudo-spectral codes combined with low-order modeling
and analysis of the equations.
Other research interests include hydrodynamics stability of jets, focusing on complex jets, and to some extent bioflows.
