My research focuses on understanding biomechanics of traumatic brain injury (TBI) and designing advanced protective devices. I collaborate with neurologists and neurosurgeons (Imperial Neurotrauma Centre) to better understand mechanisms of brain injury and their link with cognitive outcome after injury. This research will enhance our understanding of mechanisms of TBI and their link with short-term and long-term clinical outcome after TBI. In addition, it will accelerate enhancement of protective devices and environments, leading to reduced death or disability due to TBI. I am developing a research programme on optimal design of energy absorbing liners for TBI mitigation, which will inform next generation helmets along other applications in aerospace, automotive and defence industries.
I obtained my BSc (1st class honours) and MSc (distinction) degrees in Mechanical Engineering. Before joining Imperial College in 2007 for my PhD, I worked in automotive and oil & gas industries for four years as an R&D and Design Engineer. My PhD research, which was part of a collaborative EU project MYMOSA, was on designing novel test methods for improving helmet standards. The proposed methods are under review for developing new helmet standards.
We held the first international conference on Helmet Performance and Design at Imperial College on the 15th of February 2013. The proceedings of the conference are available here. You can listen to my interview with the Imperial Media team about why we should wear a helmet, here.
