NNS 2023


Welcome to Neurotrauma 2023
June 25 - 28, 2023


After the big success of the 39th Annual Symposium of the National Neurotrauma Society, including the AANS/CNS Joint Section last June in Atlanta, Georgia, the Neurotrauma 2023 team is excited to meet you again at the 40th Annual Symposium of the National Neurotrauma Society, including the AANS/CNS Joint Section. 

The symposium theme for 2023 is “Celebrating Landmarks of Neurotrauma”.

It is our pleasure to invite you to attend the 40th Annual Neurotrauma Symposium, to be held at the Austin Marriott Downtown, in Austin, Texas June 25 to 28, 2023. We are thrilled to offer professionals in the field of Neurotrauma both exceptional education sessions and meaningful networking opportunities. In 2023, we can celebrate the landmarks of our success in the marking two significant milestones, the 35th Anniversary of the National Neurotrauma Society, and the 40th Annual Symposium of the National Neurotrauma Society, including the AANS/CNS Joint Section. We can’t wait for you to join us for this significant year!

Courtney Robertson, MD

NNS President

Courtney L. Robertson, MD is an Associate Professor of Anesthesiology and Critical Care Medicine, and Pediatrics at Johns Hopkins SOM. She is the Director of the Pediatric Neurocritical Care Program in the Johns Hopkins Children’s Center Pediatric ICU. She also serves as the fellowship director of the Pediatric Neurocritical Care fellowship, and the research co-director of the Pediatric Critical Care fellowship. Her research evaluates neuroprotective strategies in pediatric traumatic brain injury, using clinically relevant models of injury. Specifically, her work focuses on mitochondrial dysfunction and neuroinflammation after TBI, and the developmental regulation of these pathways. She has been the site PI for several multi-center clinical trials in pediatric TBI, and is currently co-PI of a multinational clinical study evaluating neurologic manifestations of COVID19 in infants and children. She is a founding member and past Chair of the Pediatric Neurocritical Care Research Group.


She has been an active member of the National Neurotrauma Society for >20 years, serving on NNS council for 3 terms, and as an officer in WiNTR. She is currently serving as president of NNS.


Dr. Robertson completed her undergraduate training (Texas A&M) and medical school (UTMB) in Texas, followed by pediatric residency at University of North Carolina. Her fellowship training was in pediatric critical care at the Children’s Hospital of Pittsburgh, where she was also a research fellow at the Safar Center for Resuscitation Research.

Grace Griesbach, PhD

Program Chair

Dr. Grace S. Griesbach is the National Director of Clinical Research for the Centre for Neuro Skills and is affiliated to the Department of Neurosurgery, Geffen School of Medicine at University of California, Los Angeles (UCLA). She received her doctorate in Behavioral Neuroscience from the University of Texas at Austin under the training of National Academy of Science member, Dr. Abram Amsel. She later did her post-doctoral studies at UCLA under the guidance of Dr. David Hovda. She was the first to provide molecular basis to anecdotal observations on the timing of exercise after experimental traumatic brain injury (TBI). Dr. Griesbach has expanded her exercise research to the clinical field and is exploring mechanisms that have an influence on post-acute recovery after TBI and stroke. She has served as a President for the National Neurotrauma Society and is currently the Program Chair for the 2022 Neurotrauma Symposium.
