Dr. Orff received his doctorate in Clinical Psychology from the SDSU/UCSD Joint Doctoral Program in Clinical Psychology (2010). He completed his clinical internship at Brown University Medical School (2009) and his postdoctoral fellowship at the VA San Diego Healthcare System and UCSD Department of Psychiatry (2010-2015). Dr. Orff is currently a Health Science Research Specialist at the Veterans Affairs San Diego Healthcare System.
Dr. Orff’s current program of research aims to: 1) determine the efficacy of Cognitive-Behavioral Therapy for Insomnia (CBT-I) relative to a Sleep Education in Veterans with insomnia following mild traumatic brain injury (mTBI), 2) evaluate observed changes in sleep efficiency as a mediator of comorbid symptom improvement in this population, 3) evaluate the moderating effect of other post-concussive symptoms (e.g., depression, PTSD, pain, global functioning and disability, neuropsychological functioning, and medication use) on the CBT-I treatment outcomes, and 4) explore the potential impact of CBT-I on objective measures of sleep (e.g., polysomnography [PSG] and quantitative electroencephalography [QEEG]). Dr. Orff is funded through the VA Office of Rehabilitation Research and Development (RR&D).
