Tiago Cousseau, Ph.D., is a Professor of Contact Mechanics and Lubrication at the Universidade Tecnológica Federal do Paraná, Curitiba/PR, Brazil. He obtained a Ph.D. in Mechanical Engineering from the University of Porto, Portugal, in 2013 in grease-lubricated ball bearings. Part of his research was conducted at the Luleå University of Technology, Sweden, and the SKF Engineering and Research Center. Since then, his research has focused on the efficiency and reliability of lubricated components. The main outcome of his research work is the development of bench tests and test methods for proper lubricant selection and formulation.
