We reach across institutions and departments to bring together experts from Seattle Children’s, the University of Washington, Harborview Medical Center, the Harborview Injury Prevention Research Center, the Seattle Sports Concussion Program and other top institutions. Our team includes:

Investigators

Frederick Rivara, MD, MPH

Frederick Rivara concussion collaborativeDr. Frederick Rivara leads the Collaborative. He is the Seattle Children’s Guild Endowed Chair in Pediatric Research and is vice chair of the Department of Pediatrics. He is an internationally-recognized expert in pediatric injury research and his landmark studies – including one that showed helmets could prevent 85% of head injuries stemming from bike crashes – played a key role in dramatically increasing helmet and seatbelt use. He co-edited the 2014 Institute of Medicine report on sports-related concussion in youth and is editor-in-chief of JAMA Pediatrics.

Jalal Andre, MD

Jalal Andre concussionDr. Jalal B. Andre is director of neurological magnetic resonance imaging (MRI) and MRI safety officer at Harborview Medical Center, and a University of Washington assistant professor of radiology, with expertise in neuroradiology.

His research interests include the clinical application of advanced MRI techniques in assessing brain vessel abnormalities and traumatic brain injury. Andre’s focus involves measuring brain perfusion (blood flow) using arterial spin labeling, an MRI technique that can noninvasively measure blood delivery to the brain and requires no IV access, injectable substance or radiation.

Andre is using this technique to better understand vasospasm, a type of temporary vessel narrowing that can occur in patients with aneurysmal subarachnoid hemorrhage (i.e., a brain bleed). He is also exploring the application of this non-invasive technique to evaluate concussion, and sports-related traumatic brain injury in adolescents.

Samuel Browd, MD, PhD, FACS, FAANS, FAAP

Samuel Browd concussionDr. Samuel R. Browd is a board-certified pediatric neurosurgeon appointed as associate professor of neurological surgery at the University of Washington and attending neurosurgeon at Seattle Children’s Hospital. He is the medical director of Seattle Children’s Sports Concussion Program and currently serves as an unaffiliated neurologic consultant to the National Football League and an independent neurologic consultant to the Seattle Seahawks.

Browd was appointed as a University of Washington Presidential Entrepreneurial Fellow in 2013 and has founded three angel/venture–funded medical technology startups out of the University of Washington. Browd’s work in concussion has focused on materials science and engineering solutions. Browd’s innovations and collaborative efforts with the University of Washington Department of Mechanical Engineering have led to a new force-reducing football helmet which will be marketed under the name Vicis.

He also serves as co-investigator on several clinical outcomes studies on pediatric concussion.

Sara Chrisman, MD, MPH

Sara Chrisman concussionDr. Sara Chrisman is a pediatrician, an adolescent medicine specialist and an epidemiologist, and her research is centered around concussion. She has published multiple articles on concussion that explore concussion reporting behavior, the association between depression and concussion, and the effects of concussion legislation. Her current research is focused on understanding the mechanisms that result in concussive injury using the xPatch sensor and examining evidence for concussion treatment approaches. She is also the site principal investigator for a study jointly sponsored by the National Collegiate Athletic Association and the Department of Defense exploring concussion in varsity athletics.

Seth Friedman, PhD

Seth Friedman concussionDr. Seth Friedman is a medical physicist at Seattle Children's Hospital. He runs the Radiology Clinical Research Imaging Core, a campus-wide resource under the Center for Clinical and Translational Research.

Friedman was previously at the University of Washington in a research associate professor capacity within the Department of Radiology. His 1997 PhD was one of the first studies to demonstrate that magnetic resonance spectroscopy could be used to evaluate unseen tissue injury in head trauma and that the degree of change was associated to neuropsychological deficits and ultimate outcome.

Friedman’s recent work seeks to coordinate novel uses of imaging focused on a wide-range of neurological and systemic disease conditions (e.g., growth hormone releasing hormone treatment with aging, mitochondrial disease, thalassemia, facioscapulohumeral muscular dystrophy (FSHD), pyridoxine dependent epilepsy).

Friedman’s current National Institutes of Health–funded work examines inhibitory neurotransmitter changes in pediatric concussion and a multi-site study of FSHD integrating MRI and blood/tissue-based measures.

Christine Mac Donald, PhD

Christine Mac Donald concussionDr. Christine Mac Donald is an assistant professor in the University of Washington Department of Neurological Surgery. Her research focuses on advanced magnetic resonance methods for evaluating traumatic brain injury in the civilian and military populations.

For instance, diffuse axonal injury is thought to be a major contributor to cognitive dysfunction in patients following traumatic brain injury. However, it is difficult to diagnose antemortem and new diagnostic methods are needed. Diffusion tensor imaging has shown promise but has yet to be fully validated for its potential role as a diagnostic tool in evaluating brain injury. Resting-state functional MRI correlation analysis has also been proposed as a useful tool in the evaluation of brain functional connectivity. The basis of this method is that anatomically connected regions in the brain show correlated fluctuations in the blood oxygen level dependent signal. This work has given further insight into the structural and functional changes occurring following injury. In the future, these techniques may be able to better assist with the stratification of patients for therapeutic intervention, diagnosis of brain injury/concussion and prediction of injury impact on long-term outcome.

Cari McCarty, PhD

Cari McCarty concussionDr. Cari McCarty is a research associate professor in the University of Washington Department of Pediatrics, in both the Division of General Pediatrics and the Division of Adolescent Medicine. She is also an adjunct research associate professor in the UW’s Department of Psychology and a member of the Center for Child and Family Well-Being.
