Javier Sanchez is currently Assistant Professor of Engineering Design at Tecnun, University of Navarra, Spain. He received his MS degree in Mechanical Engineering in 1995 from Tecnun, University of Navarra. In 2006 Javier received his PhD in Mechanical Engineering, focused in computational methods for the generation, manipulation and representation of tensile membrane structures in real time, in collaboration with the civil engineering institute at Tecnun.

He started his professional career in 1995 working in the cutting tools industry as Head of the technical office at Widia Valenite Iberica in Spain and Germany. His work was focus on special manufacturing processes for the automotive and aeronautic industry.

Javier joined Tecnun in 1999 to start his research and academic career in several fields such as Computer Graphics, Civil Engineering and manufacturing. His research activities include advanced parametric surface representation and construction, NURBS curve and surface fitting, surface interpolation and approximation, analysis of presstressed net and cables, formfinding of double-curved membrane structures,  surface fitting for tensile structures models, tensile membrane design software and programming. His academic activities are related to Product Design methodologies, 3D solid and surface computer modeling techniques, covering all the stages of the product design process, from the conception of a product until its realization.

He founded the Rapid Prototyping Laboratory of Tecnun in 2004, introducing new techniques and technologies used in product design, such as clay modeling, rapid prototyping, rapid tooling, high speed machinign, injection moulding, mold making, reverse engineering, free form modeling, face scanning and 3D medical imaging processing.

He is currently involved in several research and industrial projects related to industrial design and tensile membrane structures. Javier is very enthusiastic about bringing together creativity and engineering to generate new ideas to be used in other fields such as architecture, medicine, sculpture, music, cooking or any other that would appear.
