Dr Georges Limbert is Associate Professor within Engineering and the Environment at the University of Southampton.

Dr Georges Limbert (GL) is an Associate Professor in Mathematical Modelling in Biotribology within the national Centre for Advanced Tribology (nCATS) and Bioengineering Sciences Research Group (BSRG) at the University of Southampton.
His current research focus is on the biophysical modelling of biological soft tissues and the physics-based modelling of wear of polymers for orthopaedic and tissue engineering applications. GL has expertise in continuum/computational mechanics and the development of constitutive models for biomaterials, biological tissues and structures.


Before taking on his lectureship GL was a Senior Researcher at the Wales College of Medicine at Cardiff University (2001-2007) and, more recently, a Senior Consulting Engineer (Computational Biomechanics) at the Research Institute for Industry within the School of Engineering Sciences (SES) in Southampton (2007-2009) where he assisted orthopaedic implant companies in the design and CE marking of their products using computational modelling techniques.


GL holds a Master in Engineering Mechanics (Toulouse, France) and a Research Master in Theoretical Mechanics (Bordeaux, France). He obtained a PhD in Computational Biomechanics from the University of Southampton in 2002 and is a Chartered Engineer and Member of the Institution of Mechanical Engineers (IMechE) since 2005. GL also sits on the board of the Engineering in Medicine and Health Division of the IMechE since 2004.

Research interests

Dr. Limbert is interested in understanding the physical behaviour of biological tissues in health, disease and ageing and how they interact with engineered devices (e.g. surgical implants and consumer goods) via the use of multi-physics modelling techniques. His research covers the following main themes:

  • Constitutive modelling of biological tissues and biomaterials (how we can develop mathematical and computational models capable of describing and predicting the physical behaviour of these complex materials and structures).
  • Skin biophysics and tribology (how we can unravel the biophysical interplay between the material and structural properties of the different skin layers such as the stratum corneum, viable epidermis and dermis and how to exploit this knowledge to design better consumer and cosmetic products).
  • Modelling of wear (how we can develop physics-based computational models capable of predictive the wear of surgical implants used in total joint arthroplasty and the wear of machine parts in nuclear submarine applications).
  • Chemo-mechanics of biodegradable polymers for cardiovascular tissue regeneration applications (how we can formulate multi-physics mathematical and computational models and exploit them to optimise the physical properties of biodegradable polymer-based tissue-engineered scaffolds).

How does the stiffness of a wound affect how it heals?

The healing of a skin wound is a highly co-ordinated series of events involving both biochemical and biomechanical signalling. We are trying to understanding how the mechanical properties of a healing wound affects how it heals.

How to design better artificial knee joints

The aim of this research is to gain a better understanding of the physics of wear of surgical polymer components used in knee replacement systems so that predictive computational mechanistic models can be developed to simulate in-vivo operating conditions.

Understanding the physics of wet shaving

The apparently simple act of shaving with a razor and a shave preparation involves complex multi-physics interactions. Notably, it involves the flow of a non-Newtonian, shear-thinning fluid (shave preparation) around the cartridge mechanism on top of a complex highly non-linear structural material (the skin).
