I am interested in understanding the effects of mechanical forces on the human body and designing systems that can enhance this interaction to reduce injury and improve health. I lead a group of researchers at the HEAD lab. Our focus is the biomechanics of traumatic brain injury (TBI) and designing measures for prediction, prevention and protection. For this research, we use advanced computational and experimental methods and collaborate with neurologists, industrial partners and standardisation bodies.

If you are interested in doing a PhD in my group, please send me an email.

Other roles

  • Member of the ISO and BSI head protection committees (CEN/TC158-WG11 and BSI-P/H6)
  • Member of the advisory panel of the UK Road Accidents In-Depth Analysis Studies (RAIDS) database
  • Member of the management group of the Centre for Injury Studies (CIS)


I have led two modules in our MEng Design Engineering programme: Solid Mechanics and Finite Element Analysis. I designed both modules in a way to enhance student engagement, a key contributor to deep learning. The labs that I designed for these modules have been highly rated by students: the catapult lab and the water tower lab.


My other departmental roles include:

  • 2022-present: Director of Postgraduate Studies (PhD)
  • 2016-2022: Senior Tutor
