Scientific affiliations

I am researcher of IDMEC - Instituto de Engenharia Mecanica and the coordinator of the Mechanical Engineering Scientific Area of Mechanical Design and Engineering Materials and of the NanoLab - The Nanostructured Materials and Nanotechnologies Laboratory of IST. Currently my Materials Engineering Research Group has three main materials development areas: eco-friendly cements (RL1) ; biomaterials (RL2) and tribology (RL3).
