Dr. Lyndia Wu’s research program focuses on the biomechanics of mild traumatic brain injuries, known more commonly as concussions. In order to develop more accurate measures for the mechanisms of brain injury during head impact, Dr. Wu developed a mouthguard with sensors that can be worn during physical activities in her PhD work. This mouthguard captures both the translational and rotational kinematics of head motion and the skull, detects head impact and dangerous motions of the head with high sensitivity, and may enable the discovery of more accurate predictors of injury than traditional measures. In addition, Dr. Wu investigates the short- and long-term neurological effects of head trauma. Once she has established the link between the physical mechanisms of brain injury and the resultant neurological changes, she intends to further develop wearable sensors into a real-time injury screening device.
Dr. Wu’s commitment to biomedical research stems from her passion for applying her skills in electrical engineering and bioengineering in ways that can directly benefit healthcare. She plans to continue developing wearable devices that can help gather data to characterize human diseases, and use data mining and machine learning approaches to analyze such data.
Dr. Wu collaborates with Drs. Peter Cripton and Tom Oxland at ICORD on injury biomechanics research. She has collaborated with Dr. Mehmet Kurt of the Stevens Institute of Technology, Dr. Kaveh Laksari of Arizona State University, Dr. Joel Stitzel of Wake Forest University, and Dr. Ellen Kuhl of Stanford University on brain injury biomechanics studies. She has also worked with Dr. Songbai Ji of Worcester Polytechnic Institute and Dr. Svein Kleiven of KTH on computational modelling of brain injury. Her clinical collaborators include Drs. Gerald Grant and Max Wintermark of Stanford University.
Dr. Wu’s work has led to more accurate head impact sensors in both the measurement of kinematics and detection of impacts. Through her work, it has also been discovered that helmeted impacts on the field may cause resonance of the brain, or vibrations at certain frequencies, increasing the relative motion of the brain and skull. In addition, Dr. Wu’s work found that brain injury risks in other activities, such as roller coaster rides, may lead to brain deformations on a similar level as mild sports impacts.
