Specializing in the Biomechanics of Head and Brain Injury, Dr. Lloyd has been court qualified to provide biomechanical analyses of various incidents, including:
- Motorcycle Accidents
- Automobile Accidents
- Human Factors
- Football Helmets
- Brain Injury in Sports
- Motorcycle Helmets
- Slips & Falls
Dr. Lloyd earned a Ph.D. in Ergonomics with specialization in biomechanics from Loughborough University in England in 2002. He has practiced in the field of biomechanics for over twenty years as a senior federal researcher, is board certified (CPE # 725) through the Board of Certification in Professional Ergonomics (a national board certification that is recognized in all states) and holds a certificate in cognitive rehabilitation as a Certified Brain Injury Specialist (CBIS).
Dr. Lloyd has provided Deposition and Trial Testimony on more than 65 occasions, pertaining to civil and criminal cases in the States of Florida, Georgia, Ohio, North Carolina, Arizona, Colorado, Texas and Great Britain and has been recognized as an expert in biomechanics in every case. The biomechanical analysis methods that Dr. Lloyd utilizes have been published in peer-reviewed scientific journals and have survived Daubert (Porter) challenge.
Dr. Lloyd is presently employed by the James A. Haley VA Hospital in Tampa, FL, where he holds the position of Director of the Traumatic Brain Injury Laboratory. Additionally, he hold a courtesy faculty appointment as Research Assistant Professor in the University of South Florida College of Engineering. To date, Dr. Lloyd’s work has been published in four book chapters and 31 peer-reviewed journals, as well as presented at more than 100 national and international conferences (see curriculum vitae).
Dr. Lloyd’s unique capability is in the biomechanical evaluation of helmets, specifically, football, sports and motorcycle helmets. Helmets are designed to reduce the risk of blunt force trauma to the head, however protection afforded against traumatic brain injury is inadequate by many helmet designs. Dr. Lloyd is often called upon to opine whether the head and brain injuries that a plaintiff sustained may or may not have been prevented by head protection.
Dr. Lloyd’s advanced research into helmets has lead to several peer-reviewed publications in scientific journals. Specifically, the apparatus and methods that he employs to evaluate helmet protection was published in a landmark technical article titled “Response of an Impact Test Apparatus for Fall Protective Headgear Testing Using a Hybrid-III Head-Neck Assembly“.
Using this apparatus, Dr. Lloyd and co-author / neurologist Dr. Frank Conidi of the Florida Center for Headache and Sports Neurology have presented a series of studies at the American Academy of Neurology meetings. Our work was publicized by the AAN in a press-release titled “How Well Do Football Helmets Protect Players from Concussions” Most recently, Dr. Lloyd and Dr. Conidi published a scientific article in the Journal of Neurosurgery titled “Brain Injury in Sports“, in which they document the limited protection against traumatic brain injuries afforded by many current varsity football helmets.
Dr. Lloyd’s passion is motorcycling, which, along with automobile accidents, is a leading cause of traumatic brain injuries in the United States. Dr. Lloyd has obtained certification through the Institute for Police Technology and Management (ITPM) on Motorcycle Crash Investigation, as well as certification in Reconstruction and Analysis of Motorcycle Accidents through the Society for Automotive Engineering (SAE).
Ultimately, Dr. Lloyd’s goal is to develop a new generation of advanced helmets using intelligent materials to provide protection against both blunt force trauma to the head as well as traumatic brain injuries. His research has lead to the development of Impact Absorbing Composite Materials, a patent on which has been filed with the United States Patents and Trademarks Office (USPTO). The efficacy of this design was demonstrated during the NI Week keynote presentation in 2014, which can be viewed on YouTube. Dr. Lloyd is currently exploring the utility of this patent with several helmet manufacturers to provide advanced head and brain injury protection to motorcyclists, football players and participants in many other sports that require helmet protection.
