"Multiscale Biomechanics of Brain Injury"
Michelle LaPlaca, Ph.D.
Wallace H. Coulter Department of Biomedical Engineering
Michelle LaPlaca’s broad research interests are in neurotrauma, injury biomechanics, and neuroengineering as they relate to traumatic brain injury (TBI). The goals are to better understand acute injury mechanisms in order to develop strategies for neuroprotection, neural repair, and more sensitive diagnostics. More specifically, the lab studies mechanotransduction mechanisms, cellular tolerances to traumatic loading, and plasma membrane damage, including mechanoporation and inflammatory- & free radical-induced damage. We are coupling these mechanistic-based studies with –omics discovery in order to identify new biomarker candidates. In addition, LaPlaca and colleagues have developed and patented an abbreviated, objective clinical neuropsychological tool (Display Enhanced Testing for Cognitive Impairment and Traumatic Brain Injury, DETECT) to assess cognitive impairment associated with concussion and mild cognitive impairment. An immersive environment, coupled with an objective scoring algorithm, make this tool attractive for sideline assessment of concussion in athletic settings. Through working on both basic and clinical levels she is applying systems engineering approaches to elucidate the complexity of TBI and promoting bidirectional lab-to-clinical translation.
The Parker H. Petit Institute for Bioengineering and Bioscience, an internationally recognized hub of multidisciplinary research at the Georgia Institute of Technology, brings engineers, scientists, and clinicians together to solve some of the world’s most complex health challenges. With 17 research centers, more than 170 faculty members, and $24 million in state-of-the-art facilities, the Petit Institute is translating scientific discoveries into game-changing solutions to solve real-world problems.
