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:  

 

This Professor was the pioneer and founder of the area of Microhydrodynamics and Rheology of Complex Fluids (e.g. magnetic suspensions, emulsions, elastic fluids) at the University of Brasília - Brazil. I have supervised and guided several undergraduate and graduate students who are currently researching, advising and (or) working  in that area at UnB itself and at other institutions , including companies and industry in Brazil and abroad. 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 publishing  with my supervised students.
