Dr. Alex Hartov is a Professor of Engineering at Thayer School of Engineering. Dr. Hartov received his MS and PhD in Engineering Sciences from Dartmouth College in 1988 and 1991, respectively. Dr. Hartov has collaborated with Dr. Roberts and Dr. Paulsen for over one decade as part of the Brain Research Group, and is lead investigator on an Electric Impedance Tomography Project for prostate.

Songbai Ji, DSc

| Telephone: (603) 646-9193 | Fax: (603) 646-3699
Dr. Songbai Ji is an Assistant Professor of Engineering at Thayer School of Engineering. Dr. Ji received his MS in Mechanical Engineering in 2001, and MS in Computer Science and DSc in Mechanical Engineering in 2003, all from Washington University in St. Louis. Dr. Ji has substantial expertise and extensive experience in studying brain biomechanics in both quasi-static (e.g., in image-guided neurosurgery) and dynamic impact (e.g., in traumatic brain injury) conditions using subject-specific biomechanical models and advanced imaging techniques. Within the Brain Research Group, he is heavily involved in all aspects of the brain deformation project, including designing and implementing an advanced data acquisition system for intraoperative ultrasound and stereovision, imaging analysis, and biomechanical modeling to compensate for brain deformation. In addition, he leads an effort to study brain mechanical responses subjected to impact with subject-specific brain models, which, in collaboration with other researchers, aims at better understanding the mechanisms of sports-related mild traumatic brain injury.
