Dr. Drummond started his career in sleep research when he volunteered as an undergraduate research assistant in the Sleep Research Laboratory at the University of Arizona under the direction of Richard Bootzin, PhD and Michael Perlis, PhD (then a graduate student). After college, he worked with Sarah Mosko, PhD at UC Irvine Medical Center investigating mother-infant co-sleeping. For graduate school, he attended the SDSU-UCSD Joint Doctoral Program in Clinical Psychology where he worked with J. Christian Gillin, MD. He completed his Pre-doctoral Internship at the Tucson VA hospital and then returned to the University of California San Diego (UCSD) as a Postdoctoral Fellow working with Gregory G. Brown PhD. He served on the UCSD Department of Psychiatry faculty from 2002-2014, and as a Staff Psychologist at the VA San Diego Healthcare System from 2005-2014.In those capacities, Dr. Drummond was Director of the Laboratory of Sleep and Behavioral Neuroscience, Director of the Behavioral Sleep Medicine Program, Associate Director of the Mood Disorders Psychotherapy Program, and Co-Director of the UCSD/VA San Diego Psychology Internship Training Program. Dr. Drummond joined the Monash School of Psychological Sciences as a Professor of Clinical Neuroscience in Dec 2014. In addition, he retains an Adjunct Professor appointment at UCSD and is a Visiting Professor at Northumbria University.

Dr. Drummond has also been very active with the Sleep Research Society, serving in a variety of capacities over the years, including as a committee member, committee chair, member of the Board of Directors, and Secretary-Treasurer. He currently serves as the President-elect (June 2014 - June 2016). Dr. Drummond is also a member of the Executive Committee and International Program Co-Chair of the World Sleep Federation.

 Dr. Drummond has two main arms to his program of research: 1) cognitive neuroscience of sleep and sleep deprivation; 2) treatment of insomnia, especially in comorbid psychopathology; and 3) translational research examining the mechanistic role sleep plays in PTSD and mood disorders. With respect to cognitive neuroscience, his 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 EEG. His work also includes healthy older adults and clinical populations such as obstructive sleep apnea and insomnia. He is interested in a number of cognitive performance domains, particularly decision making, attention, executive function (broadly defined) and learning/memory. Dr. Drummond’s clinical research focuses on the treatment of insomnia in various contexts. His translational research examines the interaction of sleep, sleep disruption, and psychiatric symptoms. In particular, he is interested in understanding the mechanistic role sleep plays in development, maintenance, and treatment of Posttraumatic Stress Disorder and mood disorders. His research has been funded by several sources, including the National Institutes of Health, National Science Foundation, US Department of Defense, and industry. Dr. Drummond’s clinical expertise lies in treating behavioral sleep disorders, such as insomnia and chronic nightmares, as well as mood disorders such as depression and bipolar.
