Research Interests

Research Focus

Dr. Twamley's research focuses on bridging neuropsychology and interventions for individuals with severe mental illness, history of traumatic brain injury, or other cognitive impairments. Current intervention studies focus on compensatory cognitive training (see www.cogsmart.com) and supported employment. Other research interests include cognitive impairment and disability in homeless individuals, the neuropsychology of everyday functioning, genetic markers of cognition in schizophrenia, cognitive impairment in PTSD, and the use of technology to improve cognition. Dr. Twamley’s research has been funded by NIMH, VA, Department of Defense, and the Brain and Behavior Research Foundation (NARSAD).

Clinical Focus

Dr. Twamley is a licensed clinical psychologist specializing in neuropsychological assessment, cognitive rehabilitation, and supported employment. She is the Director of the UCSD Supported Employment Program at UCSD Outpatient Psychiatric Services. Dr. Twamley is particularly interested in community-based interventions that help individuals with severe mental illness or other cognitive impairments reach their highest potential social and occupational functioning. She supervises psychology interns and practicum students at UCSD Outpatient Psychiatric Services and the VA San Diego Healthcare System. She also conducts a neuropsychological assessment clinic at the St. Vincent De Paul Medical Clinic.
