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.

Highlights and New Features  (part in Portuguese):  

A tese do nosso então aluno de doutorado Adriano Possebon Rosa (2014-2017) do Programa de Ciências Mecânicas-ENM/FT/UnB, atualmente docente do ENM e credenciado no PCMEC, foi contemplada com o Prêmio máximo UnB de Dissertação e Tese 2018/2019 (Edital DPG/UnB/008-2020), na grande área das Engenharias e com o Prêmio melhor tese do Colégio Ciências Exatas, Tecnológicas e Multidisciplinar no Grande Prêmio UnB de Tese (outubro/2020).  Intitulada “Microestrutura e Magneto-Reologia de Ferrofluids em Cisalhamento: Teoria e Simulação”, a tese foi defendida em julho/2018, teve um período de 12 (doze)  meses de Doutorado Sanduíche, com co-orientação do Prof. Hector D. Ceniceros na Universidade da Califórnia em  Santa Barbara (UCSB-USA), apoiado pelo Projeto Ciências sem Fronteiras - CNPq (grant: 402371/2013),  intitulado Multi-model Micro-Macro Approaches for the Dynamics and Rheology of Magnetic Droplets, coordenado pelo orientador.  A tese se destaca  pela sua  alta densidade científica, interdisciplinaridade, originalidade e inovação que impressionam tanto em relação aos aspectos teóricos como também as metodologias empregadas nas simulações numéricas de suspensões magnéticas usando dinâmica Browniana. É inequívoca a relevância científica e tecnológica do trabalho, demonstrada pelo impacto dos artigos científicos publicados em periódicos indexados de grande circulação internacional como o Physics of Fluids (ver publicações associadas abaixo).  Vale ainda destacar que os resultados mais relevantes da tese já estão sendo utilizados no contexto internacional por vários grupos de pesquisa que trabalham com reologia, hidrodinâmica e magnetização de suspensões magnéticas.
