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 scientific publications listed below involve the results of thesis, dissertations, final year project and scientific initiation research developed with my graduate and undergraduate students under my close supervision at University of Brasilia - ENM - VORTEX. I have highly valorized publicarions with participation of my supervised students as expected by CAPES and CNPq in Brazil.
