Professional biography:

Naveen Ravirala received his BEng (Osmania University, India) in 1999 and MPhil (University of Manchester) in 2001. He received doctorate in 2006 from University of Bolton in the area of auxetic materials investigating into the extended range of fabrication, characterisation and modelling of novel auxetic fibres and films. He has further developed his interests towards finite element modelling and characterisation techniques and is presently working at University of Bolton as a postdoctoral research fellow in a European framework-6 funded project focussed on design, development and modelling of novel sandwich core materials that can able to include in its microstructure sensors and actuators to be implemented in innovative smart sandwich panel composite structures for aerospace applications. He is actively involved in a number of key projects supervising and guiding staff and research students. His area of research interests lies in the design, modelling and characterisation of auxetic materials including fibres, films, fabrics, composites, cellular structures and foams. He is also presently working and also supervising one PhD student funded through TSB program investigating on the effect of structural materials with auxetic inclusions.

Current research interests:

• Materials modeling and characterisation.
• Auxetic polymeric extruded products.
• Auxetic foam fabrication and characterisation.
• Microscopy analysis.
