Ilenia Battiato interests lie in theoretical/computational fluid mechanics and transport processes in crowded environments; multiscale, mesoscale and hybrid methods; effective medium theories; superhydrophobicity and drag reduction; granular matter; multiphase flows; jets breakup. IIenia's research spans a wide range of scales, applications, and modeling techniques including discrete- and continuum-scale models of flow and transport processes in crowded environments (e.g., intracellular environment, carbon nanotube forests, mesoporous ultracapacitors), fluidization/jamming of granular matter, non-Newtonian jets, and effective medium theories of laminar/turbulent flows over complex surfaces (e.g., patterned and/or superhydrophobic surfaces for drag-reduction and shear control). She tackle these problems with a combination of theoretical and computational approaches including multiscale and hybrid methods, effective medium theories, perturbation methods, homogenization and up scaling techniques.
