Dr. Welch holds a Ph.D. in Biomedical Engineering awarded jointly by the Georgia Institute of Technology (Georgia Tech) School of Engineering and the Emory University School of Medicine in Atlanta, GA. Dr. Welch’s areas of expertise include the biomechanics of human injury, vehicle accident reconstruction, slip-and-fall events, occupational injury, reactive muscle activity, and human balance control and stability.
He also has experience in human motion and gait analysis; electromyography (EMG); the computer modeling of biomechanical systems; the mechanical, biochemical, and ultrasound characterization of biological soft tissue; biomedical ultrasound imaging; and statistical and wavelet analysis. Dr. Welch performs biomechanical analyses for cases involving automotive collisions, slip/trip and fall events, falling objects, occupational injury, and other incidents leading to human injury. He also performs vehicle accident reconstruction analyses for collisions involving single vehicles, multiple vehicles, and pedestrians. Dr. Welch has numerous publications on topics related to automotive collision-related injury and human standing balance control, and actively maintains collaborative research relationships with several academic institutions. Dr. Welch has offered expert witness testimony in the areas of accident reconstruction and injury causation/biomechanics in the States of Georgia, Virginia, Michigan, Florida, Tennessee, Louisiana, Alabama, and Illinois.
Dr. Welch has over 20 years of biomechanics research experience, studying human movement on multiple levels:
Injury – the forces present on the body during automotive collisions; mechanics – the effects of forces on the bony and soft tissues underlying human movement Coordination – the activation of muscles in functional groups called muscle synergies Control – the mechanisms used by the nervous system to control standing balance and to learn new balance tasks Performance – the effects of supplements on sport and exercise performance
