I am interested in understanding the effects of mechanical forces on human body and designing systems that can enhance this interaction. I lead a group of researchers at the Extreme Conditions Lab (ECL). Our current focus is biomechanics of traumatic brain injury (TBI) and designing advanced protective devices. For this research, we use advanced computational techniques and design tools and collaborate with neurologists and neurosurgeons at Imperial Neurotrauma Centre. This work will improve head protection systems and treatment, leading to a reduction in death and disability after TBI.

My areas of interest are:

  • Biomechanics
  • Computational mechanics
  • Energy absorbing materials
  • Safety standards

My key publications in these areas are: Brain, Peridynamics, Oblique impacts.


  • Imperial College Research Fellowship, 2013
  • Young Researcher Award of the International Research Council of Biomechanics of Injury in 2009 for my work on helmet standards
  • Best presentation award of the Dementia Research Symposium, 2017

Industrial collaborations

I have consulted on a number of industrial projects. I currently work with Transport Research Laboratory (TRL) and St Mary's Major Trauma Centre on a research project related to TBI in road collisions, co-funded by EPSRC CDT in Neurotechnology.

Other roles

  • Member of the ISO head protection committee (CEN/TC158-WG11)
  • Member of the BSI head protection committee (BSI-P/H6)
  • Member of the management committee of the COST Action TU1407
  • Chartered engineer (CEng) and member of IMechE
  • Fellow of Higher Educational Academy (FHEA)



I lead two modules in our MEng Design Engineering programme, 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:

  • Senior tutor
  • Member of the admission team
  • Member of the HPX research theme
