Dr. Allin's expertise is in the analysis of human movement and injury mechanics, with specialization in evaluating slip, trip, and fall events. She has extensive experience using kinematic and kinetic data to assess human motion and injury risk. She has conducted numerous studies on slips, trips, and falls, workplace fatigue, and sports performance, and has expertise in the collection and analysis of biomechanical data using high-speed motion capture, force transducers, inertial measurement units (IMUs), and electromyography (EMG).

Prior to joining Exponent, Dr. Allin was a graduate research assistant in the Occupational Ergonomics & Biomechanics Laboratories at Virginia Tech and the Motion Biomechanics Lab at Texas A&M University. Her research involved investigating kinematic reactions to slipping, as well as evaluating balance training interventions to reduce fall risk. Additionally, she has assessed the effects of occupational fatigue on gait and fall risk. Dr. Allin also has experience in sports performance and injury biomechanics as a biomechanical analyst in the SPEED (Strength, Power, Endurance, Education, and Development) Clinic at the University of Virginia.
