I am a Senior Lecture professor at the Universidad de Sevilla in the Mechanical Engineering and Material Department. My major academic topics are: Aerospace Material, Material Industrial Process, Basic Material Technology and Material Science lectures.

My research is focused on the production of porous camphene-base Ti parts by directional freeze casting. Assessments are mainly motivated to produce high and gradient porosity. Medical application for orthopedic replacement is the main application target. The principal goal is to manufacture a gradient porous sample with a 50-70% porous fraction and diameter no less than 50 microns. Both of this aspect will allow to reduces the gap between Ti young modulus (110 GPa) and bone (10-30 GPa).
