Research:
I am the scientist leader of the Fluid Mechanics of Complex Flows Group and the Microhydrodynamics and Rheology LAB at University of Brasilia. My current research interests include: rheology of complex fluids; hydrodynamic of magnetic fluids, non-Newtonian fluid dynamics, microhydrodynamics of active and passive particles in suspensions; and mechanics of mobile suspensions in general. My research is highly interdisciplinary.
Supervision:
Most of the scientific publications listed below involves results of thesis, dissertations, final year project and scientific initiation research developed with my graduate and undergraduate students at University of Brasilia - ENM - VORTEX. I have highly valorized publicarions with participation of my supervised students.
