About John B Williamson

Neuroscience has always fascinated Dr. Williamson. As an undergraduate, he volunteered in two psychology research laboratories, one animal neuroscience, and one human psychology. These experiences lead him to pursue education in neuropsychology, where he could blend basic and applied science to understand brain and behavior relationships. At first,he was quite focused on healthy people, but then he completed an internship at The University of Chicago in their psychiatry department, and neurological underpinnings of emotional disorders strongly sparked his interest. The idea that emotional and cognitive dispositions, could change dramatically with neurological injury (e.g., in the context of frontal lobe injury from traumatic brain injury) was intriguing.

Since then, Dr. Williamson has worked to both understand mechanism of brain dysfunction in disorders such as PTSD and cerebrovascular disease, and to develop applied solutions to the problems that most impact quality of life in individuals that struggle with these issues.

Clinically, Dr. Williamson focuses on adult populations that have questions of neurological contributions to cognitive impairment. This includes patients with cerebrovascular disease (e.g., stroke) and suspected vascular cognitive impairment, traumatic brain injury, and neurodegenerative diseases (e.g., Alzheimer’s disease).

Dr. Williamson is interested in the role of central and peripheral autonomic nervous system interactions in modifying or regulating brain states and behavioral output. He has current funding in NIH funding to understand the role of cardiac output modification in changing cognitive outcomes and brain health in patients with heart failure. He also has VA funding to understand the mechanistic contribution of white matter injuries in key central autonomic inputs from traumatic brain injury and manifestation of symptoms of post traumatic stress disorder.
