I am an Associate Professor at University of California, San Diego, as well as Director of the Behavioral Sleep Medicine Program and Associate Director of the Mood Disorders Psychotherapy Program at the VA San Diego Healthcare System. I have been involved in sleep research since 1991 when I was an undergraduate at the University of Arizona. My program of research has two main foci: 1) the impact of experimental and operational sleep and sleep deprivation on cognitive performance, brain function, clinical symptoms and quality of life; and 2) the treatment of sleep difficulties in comorbid psychopathology.

Typically, my experimental studies manipulate sleep deprivation in healthy adults and measure the consequent cognitive and cerebral changes through behavioral and cognitive testing, functional magnetic resonance imaging (FMRI), and/or EEG. In addition to experimental studies in young healthy normal control subjects, my work has included healthy older adults and clinical populations such as obstructive sleep apnea and insomnia. I am interested in a number of cognitive performance domains, particularly learning and memory, executive function, attention, and decision making. The overall goals of this line of work are to: 1) better understand the impact of sleep and sleep loss on cognition; 2) predict individual vulnerability and resiliency to sleep loss; and 3) design interventions to mitigate against the negative effects when sleep deprivation is unavoidable. My clinical studies currently examine treatment of sleep difficulties in Posttraumatic Stress Disorders (PTSD), and I also have an interest in the treatment of insomnia in mood disorders. My research has been funded by several sources, including the NIH, NSF, Army, Navy, DARPA and industry.
