I have been working at Vale since 1979.

During this period, I worked in several areas: production, quality control and production planning of iron ore pelletizing plants in Brazil and in Bahrein, research and development in the pelletizing area, production of titanium ore concentrates and metallic titanium, operational excellence program for Vale's pelletizing plants in Brazil and technical marketing of ferrous products for direct reduction and blast furnace processes.

I currently work in the Technical Marketing Department of Vale in Brazil, supporting Technical Marketing activities for the Chinese market.
