Clinical Interests
Dr. Schweitzer is a licensed psychologist offering evaluations for attention-deficit/hyperactivity disorder (ADHD) and treatment for ADHD. She has expertise in ADHD across the life-span from childhood through adulthood. She sees patients at the MIND Institute Clinic.
Research/Academic Interests
Dr. Schweitzer's work is translational in nature where she uses cognitive neuroscience and behavior analytic principles to investigate attention, hyperactivity, impulsivity and regulation in children and adults in typical development and in ADHD. She has a lengthy history of using neuroimaging techniques to explore brain-behavior-environmental relationships in ADHD, including the developmental trajectory of self-control in typically developing adolescents and young adults and in ADHD. In addition, she tests and develops tech-based interventions using virtual reality and computerized game play with the goal of improving attention, self-control and academic functioning in ADHD and related diagnoses (e.g., autism).
Dr. Schweitzer is active in training translational scientists and supporting mentoring relationships through the UC Davis Clinical and Translational Science Center.
