Dr. James Hoelzle, PhD (Principal Investigator)

Dr. Hoelzle received his undergraduate degree in psychology from the University of Illinois, Urbana-Champaign. He completed his doctoral work in Clinical Psychology at the University of Toledo specializing in Assessment. He has attained extensive training in clinical neuropsychology through a two-year Neuropsychology Fellowship at the Minneapolis VA Medical Center and Clinical Internship at Rush University Medical Center (Chicago, Illinois). Clinical interests primarily consist of evaluating individuals who are experiencing cognitive and/or psychological difficulties.
Dr. Hoelzle has conducted numerous studies investigating the core constructs evaluated by neuropsychological and personality instruments, and whether these factor structures are replicable across samples and consistent with clinical theories. He contributes to research investigating cognitive outcomes in mild traumatic brain injury (concussion), attention-deficit/hyperactivity disorder, and Covid-19. Broadly, the goal of his research is to identify which individuals are at risk of experiencing persisting neurocognitive symptoms. Dr. Hoelzle is also interested in how insufficient effort on neuropsychological measures and exaggerated emotional distress is identified in different clinical settings.
