Research Interests

  • Orthopaedic Biomechanics
  • Injury Biomechanics
  • Neurotrauma (Spinal Cord and Brain Injury)
  • Biomechanics of Hip Fracture
  • Injury Prevention

Current Research Work

  • Pro-Neck-Tor’ Helmet:  Prevents spinal cord injuries (SCI) during head-first impacts that can occur during sports and transportation accidents. Awarded a “Best of What’s New” award by Popular Science for this helmet. Actively commercializing this helmet, underlining both the improved brain injury protection and the spinal column and spinal cord protection provided by its shell.
  • Neck muscle activation and cervical spine posture during automotive rollovers.
  • Neck injury criteria for head-first impacts that happen with lateral bending (head leaning sideways).
  • Spine degeneration and geriatric spinal cord injury.
  • Cerebrospinal fluid dynamics during an SCI and the role of pressure variation of this fluid on the patient during clinical treatment.
  • Finite Element Analysis of the spine during head-first impacts.
  • Safe medical evacuation of soldiers suffering from an SCI.
  • Biomechanics of spine implants.
  • Efficacy of snowboard helmets during head first impacts on snow
  • Bicycle helmet performance and testing methods.
  • Skull accelerations during headfirst impacts by hockey players.
  • Regional brain deformation and injury during head impacts leading to concussion
  • Biomechanics of Hip Injury: Studies the basic mechanisms of hip fracture using cadaveric specimens and high speed data collection. One aim of this research is to identify features in the bone architecture that predispose a specific hip to early fracture. This information can be used in preventative screening.
  • Bicycle safety improvement through infrastructure design, in association with Kay Teschke.
