Margaret Bradley, PhD

Dr. Bradley received her doctorate in Experimental (Cognitive) Psychology from the University of Wisconsin-Madison. She is currently a research professor and the associate director for NIMH Center for the Study of Emotion and Attention. Research interests focus on studying the neural and physiological mechanisms involved in affective and attentional processing in people with and without diagnosable anxiety disorders. Drawing on an animal model of motivation, our lab is mapping the subcortical and cortical neural circuits involved in emotional perception and imagery. In addition to investigating neural processes using fMRI and dense-sensor EEG, we measure autonomic and somatic indices of affective and attentional mobilization, including cardiovascular, electrodermal, electromyographic, eye movement, and other physiological measures. How emotion and attention affect later memory performance, measured in both the brain and body, is another active research area.

John WilliamsonJohn Williamson, PhD

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.
