Director

Professor of Psychiatry, UC San Diego

Director, Clinical Research Unit, Center of Excellence for Stress and Mental Health

VA San Diego Healthcare System

Dr. Twamley is a Professor of Psychiatry at UC San Diego (UCSD) and the Director of the Clinical Research Unit of the Center of Excellence for Stress and Mental Health (CESAMH) at the VA San Diego Healthcare System (VASDHS). Dr. Twamley earned a PhD in Clinical Psychology from Arizona State University and completed her clinical psychology internship and postdoctoral fellowship at UCSD and VASDHS. She is a faculty member in the SDSU/UCSD Joint Doctoral Program in Clinical Psychology (clinical neuropsychology and experimental psychopathology tracks); a faculty member of the Stein Institute for Research on Aging (SIRA) at UCSD; and Co-Director of the UCSD Research Fellowship in Geriatric Mental Health.

Dr. Twamley's research focuses on cognitive interventions for individuals with neurological and psychiatric conditions. Pursuing a longstanding interest in the links between cognition and everyday functioning, she has developed compensatory cognitive training interventions (see www.cogsmart.com) for people with psychiatric illness, traumatic brain injury, and mild cognitive impairment, and other neuropsychiatric conditions. These manuals have been adapted for other populations (e.g., autism, Parkinson’s disease, multiple sclerosis, post-traumatic stress disorder, HIV, and hoarding) and translated into multiple languages. Other research interests include cognitive impairment and disability in homeless individuals, supported employment, the neuropsychology of everyday functioning, cognitive impairment in PTSD, and the use of technology to improve cognition. Dr. Twamley’s research has been funded by awards from NIH, VA, DoD/CDMRP, NSF, and BBRF/NARSAD.

Dr. Twamley is an active teacher and mentor whose trainees include undergraduates, doctoral and medical students, and postdoctoral fellows. She is a licensed clinical psychologist specializing in neuropsychological assessment, cognitive rehabilitation, and supported employment. Dr. Twamley is particularly interested in community-based interventions that help people reach their highest potential social and occupational functioning. She supervises neuropsychological assessments at the St. Vincent de Paul Village Family Health Center, serving the largest homeless shelter in San Diego.

Recent Alumni

Dr. Jillian Clark is a fellow in the VA Center of Excellence for Stress and Mental Health. She earned her Ph.D. in Clinical Psychology, with emphasis in Clinical Health Psychology, from the University of Missouri-Kansas City. Dr. Clark completed her pre-doctoral internship at VA San Diego/UC San Diego.

Dr. Clark’s research interests center on examining biological, psychological, and social experiences in individuals with neurotrauma (e.g., spinal cord injury and traumatic brain injury) and chronic illness. She is particularly interested in identifying modifiable biopsychosocial risk factors to inform interventions aimed at improving functional outcomes across the lifespan in these populations.

Doctoral Students

Amber is a first-year graduate student in the SDSU/UC San Diego Joint Doctoral Program in Clinical Psychology, in the clinical neuropsychology track. Upon earning a BA in Psychology at UCSD, she worked as a research associate for several neuropsychological research studies at the VA San Diego Healthcare System. Her research and clinical experiences span across diverse populations such as civilians and/or Veterans with mild cognitive impairment, schizophrenia, PTSD, traumatic brain injury, and depression.

Amber's interests are in treatment development research aimed at improving emotional, cognitive, and functional outcomes in individuals with psychiatric illness and cognitive disorders. Specific interest areas include associations between clinical symptomatology and cognitive functioning in older adults, as well as in individuals with severe mental illness; the use of technology for fostering independence in older adults; and suicide prevention in individuals with complex psychiatric illness and cognitive disorders (e.g., PTSD/TBI, MCI, and schizophrenia).

Zanjbeel Mahmood is a fourth-year doctoral student in the SDSU/UC San Diego Joint Doctoral Program in Clinical Psychology, with a focus in neuropsychology. Her research converges at the intersection of neuropsychology and rehabilitation science, focused on examining the neurocognitive and functional consequences of neurodegenerative disease and severe mental illness. In particular, she is interested in characterizing the mediators and moderators that hold potential to reduce functional disabilities of disease. Zanjbeel is also interested in leveraging cutting-edge technology (e.g., biosensors, wearables) and advanced statistical models within her research to develop integrated cognitive and behavioral interventions to promote brain health and improve patient outcomes. Her work has been presented at both national and international conferences and published in several peer-reviewed journals including the Journal of the International Neuropsychological Society, Alzheimer’s & Dementia, Schizophrenia Research, and Health Psychology.
