David Francis Marshall, PhD

I am a Board-Certified Clinical Neuropsychologist, Clinical Associate Professor of Psychiatry, and Clinical Director of Neuropsychology in the Department of Psychiatry. My clinical practice spans diverse populations across the lifespan, with specialized expertise in complex psychiatric and medical disorders. I have a particular clinical focus on epilepsy and other neurological disorders.

Teaching and mentoring are central to my professional mission. I train future neuropsychologists through our APA-accredited postdoctoral fellowship and mentor fellows engaged in epilepsy research. As an invited lecturer, I instruct Psychiatry and Neurology residents and fellows on topics such as neuropsychological assessment, epilepsy care, and the Wada test.

Beyond my clinical and academic roles, I am deeply committed to service. I actively participate in departmental and university committees and have taken on leadership positions with national organizations in neuropsychology and epilepsy. Through these efforts, I strive to advance the field and support the next generation of clinicians and researchers.

As a co-investigator with the Heinz C. Prechter Bipolar Research Program, my research centers on understanding how comorbid conditions influence the trajectory of bipolar disorder. I am particularly interested in the interplay between cognitive and affective processes and how factors such as substance use disorders and adverse childhood experiences affect outcomes. In addition, I study the cognitive, psychological, and behavioral outcomes associated with epilepsy, with a focus on the effects of surgical interventions.
