Susumu Ejima, PhD

Research Associate Professor, General Surgery
Lead Biomechanics Engineer, International Center for Automotive Medicine


Susumu Ejima, Ph.D., is a Research Associate Professor in the Department of Surgery and the lead biomechanics engineer at the International Center for Automotive Medicine (ICAM). Dr. Ejima completed his doctorate in computational mechanics at Seikei University in Japan in 1997 and took a post-doctoral fellowship in mechanical engineering at the University of Michigan from 1997 to 1998. Before he returned to University of Michigan, he led Impact Biomechanics for 13 years at the Japan Automobile Research Institute. Here, he organized a role model for an "Integrated Safety" vision by generating research on three topics: the pre-crash, the crash, and the post-crash.

His primary research interest is to investigate the mechanisms of traumatic injury from real-world motor vehicle crashes using analytic morphomics, which can extract body features from the Computed Tomography (CT) scans of patients. Dr. Ejima has investigated the associations between morphomic variables and injury outcomes by linking the ICAM crash injury database to analytic morphomics, and has consistently found that morphomics provides better information in the crash safety arena.

Dr. Ejima’s past work includes the development and application of the computer human model by using CAE (Computer Aided Engineering). Currently, he is extending his research not only to prevent injury through application in the automotive industry but also to improve medical care in the healthcare space.
