UCSD Department of Psychiatry Professor since 2003 and Director of the Clinical Research Unit at the VA San Diego Center of Excellence for Stress and Mental Health, Elizabeth W. Twamley, PhD runs a clinical neuropsychology practice at 140 W Arbor Drive on the UC San Diego Health Hillcrest campus. Her work bridges cognitive assessment and rehabilitation for adults with traumatic brain injury, schizophrenia, and PTSD, with treatment delivered inside the clinical neuroscience network anchored by Hillcrest Medical Center at UC San Diego Health. Twamley co-developed CogSMART, a structured compensatory cognitive training protocol that has been adapted for veterans with mild TBI, individuals with severe mental illness, and adults with mild cognitive impairment, and is taught nationally through the CogSMART curriculum. Her PhD in Clinical Psychology came from Arizona State University and her clinical internship and postdoctoral training were completed at UCSD and the VA San Diego Healthcare System, where she now directs the NIMH T32 Geriatric Mental Health Fellowship. The cognitive assessments produced here feed into adjacent UCSD Psychiatry programs studying HIV and substance-use neurocognitive disorders, including the addiction and neuroAIDS work led by colleagues such as Dr. Igor Grant, MD. The highest-complexity cases involve Supported Employment trials for veterans with both cognitive impairment and PTSD, where Twamley pairs compensatory cognitive remediation with vocational placement and tracks return-to-work outcomes against neuropsychological baselines.
