In Memoriam

Dr. Xiao-Ming Xu

In 2023, the National Neurotrauma Society (NNS), in a joint effort with the Chinese Neurotrauma Scholar Association (CNSA) announced the establishment of the “NNS Dr. Xiao-Ming Xu Diversity Memorial Award”. This award serves to honor Dr. Xiao-Ming Xu, an internationally-renowned scientist for his significant contributions to the advancements in spinal cord injury (SCI) research and his unwavering support of diversity trainees.

Dr. Xu received his graduate education in China and the United States. He received his Medical Diploma and a master’s degree from Shanghai Jiaotong University School of Medicine (previously known as Shanghai Second Medical University).  He subsequently completed his Ph.D. in Anatomy and Neurobiology at The Ohio State University in 1990, and a postdoctoral fellowship in 1994, under the mentorship of Dr. Mary Bunge, at the Miami project to Cure Paralysis, University of Miami.

In 1994, Dr. Xu accepted his first faculty position in the Department of Anatomy and Cell Biology at St. Louis University, achieving the rank of Associate Professor.  In 2001, he was recruited to the University of Louisville, where he was named the James R. Petersdorf Endowed Chair in the Department of Neurological Surgery and helped establish the Kentucky Spinal Cord Injury Research Center as he transitioned from Associate to Full Professor.

Since 2007, Dr. Xu served as the Scientific Director of the Spinal Cord and Brain Injury Research Division at Stark Neurosciences Research Institute, Professor and Mari Hulman George Chair of Neurological Surgery at the Indiana University School of Medicine, and a Research Career Scientist at the Richard Roudebush VA Medical Center in Indianapolis.  His research focused on understanding the cellular and molecular mechanisms that contribute to secondary injury after SCI with the objective of developing neuroprotective and neurorestorative strategies to improve neurological outcomes.  He championed the pathway toward regeneration, using research that relied on diverse biochemical, physiological and bioengineering approaches.  This is exemplified in his studies that examined cell transplantation, gene therapy, and tissue engineering, with the objective of promoting axonal regrowth, myelination, and the restoration of function.

Dr. Xu served as the Editor-in-Chief of the cross-disciplinary journal, Neural Regeneration Research (http://www.nrronline.org/).  This platform was effective in bringing together researchers from different disciplines, including neuroscience, molecular biology, chemistry, immunology, and bioengineering, to address the broad biological challenges imposed by SCI.  Such collaborations generated significant impact by fostering innovation and a clear pathway toward therapeutic breakthroughs.  This was also the foundation for the establishment of the International Neural Regeneration Symposium for which Dr. Xu served as co-chair from 2011-2020.

Throughout his career, Dr. Xu promoted national and international interdisciplinary collaborations, which represented a rich diversity of talented scientists.  He actively mentored and educated the next generation of scientists including undergraduates, graduate/medical students, postdoctoral fellows, and junior faculty members.  In order to prioritize and support under-represented students and trainees, Dr.

Xu served as a regular committee member for the NIH Diversity K award and NINDS Diversity K01 and K22 applications.  And, as the Founding President of the CNSA, established in 2010, Dr. Xu’s leadership, vision, and commitment to advancing neurotrauma research, has created an environment that has fostered networking opportunities at all levels of expertise, promoting knowledge sharing and professional development.  These collective efforts have served to build a bridge of knowledge that has advanced our understanding of mechanisms underlying loss of function and aberrant pain, critically important steps in the identification of novel therapeutics that are specifically tailored to SCI and neurotrauma.  Dr. Xu has been recognized by a number of awards, including his listing in the “World’s Top 2% of Scientists 2020”, an honor that speaks to his dedication and accomplishments in the field.

Dr. Harvey Levin

Harvey Steven Levin, PhD passed away peacefully on April 1, 2022.

He was born on Dec. 12, 1946, in New York City to Nathan and Mary Levin. A graduate of the City College of New York, he earned a doctorate in psychology at the University of Iowa under the tutelage of Arthur Benton, Ph.D. and completed his internship in psychology at the Illinois Masonic Medical Center in Chicago.

Harvey was a board-certified neuropsychologist and clinical psychologist and joined the faculty at the University of Texas Medical Branch in Galveston where he began an internationally renowned career in clinical work, teaching, and, most of all, pioneering research on traumatic brain injury. In 1995, Harvey established the Cognitive Neuroscience Laboratory at Baylor College of Medicine within the Department of Physical Medicine & Rehabilitation, which was supported by federal grants, including funding from the National Institutes of Health, Department of Defense, the Department of Veterans Affairs, and the Centers for Disease Control and Prevention. The CNL integrates rehabilitation and neuroplasticity research with multimodality brain imaging, cognitive psychology, and neuropsychology. The lab focuses on multidisciplinary TBI research involving adult and pediatric populations and has pursued both observational studies and clinical trials. Harvey researched sports-related concussion, and in his joint appointment at the Michael E. DeBakey VA Medical Center, Harvey also researched mTBI sustained by veterans in combat. Click here to read the memoriam in full. 

Dr. Marion Murray

I am sad to inform you that Dr. Marion Murray, professor emeritus in the Department of Neurobiology and Anatomy, passed away on September 9 following complications of esophageal cancer.

Dr. Murray was a founding member of our Spinal Cord Research Center, leading its research activities for over 30 years to create one of the most prominent centers in the United States. She inspired and mentored countless students, fellows and faculty, established a world-class research program and published more than 150 scientific articles and reviews. She exemplified a scientific leader who passionately confronted significant problems for human health and then generously shared her knowledge with others. The focus of her research was on neuroplasticity and its relation to recovery of function after spinal cord injury, studying the role of axonal regeneration and sprouting, neuroprotection, and restoration of function lost following injury.

Dr. Murray received her PhD from the University of Wisconsin in physiology and did her postdoctoral work at McGill University in anatomy and at the Rockefeller University in neurobiology. She was appointed assistant professor in the Department of Anatomy at the University of Chicago, and in 1973 moved to our predecessor school the Medical College of Pennsylvania.

Motivated by the devastating impact of damage to the spinal cord on patients and their families, Dr. Murray and her colleague the late Dr. Michael Goldberger forged an interactive group to discover the mechanisms of injury and interventions towards recovery of function in this major clinical problem. Under her leadership, the center established multidisciplinary research training in spinal cord injury and created a program that has had international impact, with influence in basic and translational neuroscience beyond her initial vision.

Dr. Murray received numerous awards, including the NIH Javits Neurosciences Investigator Award, the Fogarty Fellowship, the MCPHU Research Achievement Award and, most recently, the Reeve-Irvine Research Award. She served on the editorial boards of scientific journals such as Experimental Neurology and Journal of Comparative Neurology; on scientific review committees, including for the NIH and the VA; and as the scientific director of the Craig H. Neilsen Foundation, one of the major private foundations focused on spinal cord injury.

Raymond Grill, PhD

On May 30, 2018 we lost a truly remarkable person when Raymond Grill, passed away unexpectedly of a heart attack. Following our announcement of his passing, we witnessed an outpouring of sorrow from Ray’s friends, students, and fellow scientists. To us, Ray was a gifted scientist, tireless mentor, valued member in our scientific community, an early member and ardent supporter of Mission Connect. One of his former student’s, Jennifer Dulin, Ph.D., shared her thoughts with her fellow members of Mission Connect. No one could have described Ray more accurately and I would like to share this with you.

“Ray was a very rare type of individual who has been a force for good in the lives of practically everyone who has known him. He was an unusually selfless person who was fully dedicated to helping others. He always, always kept the focus of his work tightly centered on the issue of “How is this going to improve the lives of people living with a spinal cord injury or traumatic brain injury?” It can sometimes be easy to lose track of the real-world relevance of our research, but Ray never let his students forget it. He was a moral compass in that sense. He was in this business for no other reason than his burning need to figure out ways to help ease some of the burdens carried by these individuals and their loved ones. This is the mindset we should all keep.

Aside from research, he was also a uniquely compassionate person who gave himself fully to everyone who asked of him. He has taken so much of his time to give advice, lend an ear, and mentor an immense number of students/trainees/junior faculty over the years. He has helped many of his friends to cope and pull through during times of crisis. He was always nonjudgmental, loving and kind, but honest, practical and straightforward. He really, really cared about people, and would do anything in his power to help those who fell on hard times. I think that there is no greater or nobler thing you can do in life than that.”

Timothy Schallart, PhD

Timothy Schallert, age 68, died on May 29, 2018 at his home in Austin Texas, with his wife, Diane, and sons, Robbie and Kellan, by his side. He had advanced Parkinson's Disease. Tim received his PhD in 1976 working with Ernest P. Lindholm at Arizona State University, followed by postdoctoral training with Ian Q. Whishaw at the University of Lethbridge and Philip Teitelbaum at the University of Illinois, Champaign-Urbana. In 1979 he joined the faculty of the Psychology Department at the University of Texas at Austin, where he remained until he retired and was named Professor Emeritus in 2017. He was also an Adjunct Professor at the University of Michigan School of Medicine and Adjunct Research Scientist at Henry Ford Health Medical Center.

Tim was broadly interested in brain-behavioral interactions, especially in the context of neural repair and plasticity responses to CNS injury and neurodegeneration. He was prolific, authoring more than 250 articles, which have been cited more than 20 thousand times. His discoveries that behavioral manipulations potently affect degenerative and regenerative responses to CNS damage had profound impact in shaping current understanding of the experience-dependency of these processes.

That Tim was often called a "rat neurologist" or " rat whisperer" reflects that he was also a driving force in the behavioral level refinement of rodent models of CNS injury and disease. He developed or helped refine many of the sensitive assays now in common use with such models, including the Schallert cylinder, bilateral tactile stimulation (a.k.a. "sticky tape"), ledged tapered beam, vermicelli handling, and corner tests.

Tim leaves behind a large scientific family of adoring colleagues, collaborators and mentees. To us, Tim was not merely a great scientist, he was a seemingly indefatigable force of nature, a wildly inspiring communicator, a role model, a champion, a person with whom it was endlessly fun to talk science, and a very dear friend who is now deeply and painfully missed.
