Dr. Welch's areas of expertise include the biomechanics of human injury, occupant kinematics and occupant restraints, slip-and-fall events, occupational injury, reactive muscle activity, and human balance control and stability. Dr. Welch has offered expert testimony in the fields of accident reconstruction and injury biomechanics in Federal, State, and local Courts throughout the United States.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 neural mechanisms used to control standing balance and to learn new balance tasks - Performance: the effects of supplements on sport and exercise performance.Dr. Welch performs injury analyses for cases involving automotive collisions, slip and fall events, falling objects, occupational injury, and other incidents leading to human injury. Dr. Welch has numerous peer-reviewed publications and actively maintains collaborative research relationships with academic institutions.
