Advancing the Understanding of Biomechanical Parameters Associated with Mild Traumatic Brain Injury
Funded by the National Operating Committee on Standards for Athletic Equipment and with close collaboration with The Geisel School of Medicine at Dartmouth and Simbex, this project uses finite element models to parametrically simulate brain mechanical responses when the head is subjected to impact recorded from on-field contact-sports events. The focus of the project is to understand the influence of model parameters (e.g., material properties, location and severity of impact, etc.) on the magnitude of brain mechanical responses.
Disciplines: Biomedical, Materials, Mechanical Systems
Additional Information: A BS or MS in mechanical or biomedical engineering or a related field is required. Familiarity with computer modeling and Matlab programming is preferred but can be learned during the execution of the project. Consideration will be given to enthusiastic and motivated applicants who can self-learn. Interested students are welcome to contact Songbai Ji via email before applying to confirm qualifications or ask questions. Please include a statement of interest, relevant experience, and a CV in your email.
