1 TAMARA L. COHEN, Ph.D. PROFESSIONAL BIOGRAPHICAL OUTLINE BACKGROUND Dr. Cohen received a Bachelor of Science in Mechanical Engineering with a minor in Bioengineering from The Pennsylvania State University. She went on to obtain her Doctor of Philosophy in Biomedical Engineering from Marquette University in Milwaukee, WI. Her scientific research focused on the biomechanics and tissue mechanics of severe clubfoot. Clubfoot is a congenital deformity of the lower extremity that, untreated, results in pain as well as abnormal ambulation and inability to navigate the physical environment, such as walkways and stairs. She utilized motion capture technology and mechanical testing to evaluate the viscoelastic response of conservative correction, as well as to quantitatively characterize the time-dependent behavior of the ligamentous component of the deformity. Dr. Cohen has experience in lower and upper extremity kinematics and kinetics of normal and pathologic populations and has worked in clinical environments with patients with impairments associated with abnormal gait. She has led workshops and lectures on motion capture technology and analysis, as well as tissue mechanics and responses to forces. Dr. Cohen is experienced in communicating with technical and nontechnical audiences alike, through classroom lectures, conferenced presentations, and entrepreneurial endeavors. She specializes in slip, trip, and fall analysis, human factors, and biomechanical and injury causation analysis.
