David S. Shannahoff-Khalsa is a researcher in mind-body dynamics.  He has published widely in scientific journals and regularly presents full day courses at the American Psychiatric Association and other national and international conferences.  Shannahoff-Khalsa has also published three books outlining his years of experience using Kundalini Yoga meditation as taught by Yogi Bhajan to understand and treat psychiatric disorders.

Scientific Publications
David Shannahoff-Khalsa first published scientific papers in the Journal of Organic Chemistry in 1973, Cancer Research in 1974, and Biochemistry in 1978. His scientific career started in 1970 at the Salk Institute for Biological Sciences in La Jolla with working in the field of nucleic acid chemistry and biochemistry on unique chemical substitutions in nucleosides, nucleotides, and polynucleotides as potential anti-viral and anti-cancer agents. He later changed fields and started work on concepts and techniques from yogic medicine in 1976 while at The Salk, demonstrating how the nasal cycle is tightly coupled to the ultradian rhythm of alternating cerebral hemispheric activity (Werntz DA, Bickford RG, Bloom FE, Shannahoff-Khalsa DS, Alternating Cerebral Hemispheric Activity and the Lateralization of Autonomic Nervous Function. Human Neurobiology, 1983, 2:39-43), and on the yogic technique called unilateral forced nostril breathing (UFNB) where they demonstrated via EEG the selective hemispheric stimulation by UFNB (Werntz DA, Bickford RG, Shannahoff-Khalsa DS, Selective Hemispheric Stimulation by Unilateral Forced Nostril Breathing, Human Neurobiology, (1987), 6:165-171). He later wrote reviews on these topics (Shannahoff-Khalsa DS, The Ultradian Rhythm of Alternating Cerebral Hemispheric Activity, International Journal of Neuroscience, 1993, 70:285-298, Shannahoff-Khalsa DS, Lateralized Rhythms of the Central and Autonomic Nervous Systems, International Journal of Psychophysiology, 1991, 11:225-251, and again in "Selective Unilateral Autonomic Activation: Implications for Psychiatry" (a review article), CNS Spectrums: The International Journal of Neuropsychiatric Medicine, 12(8), pp. 625–634, Aug 2007, and most recently in Shannahoff-Khalsa in Psychophysiological States: The Ultradian Dynamics of Mind-Body Interactions, In the series “International Review of Neurobiology,” Academic Press (Elsevier Scientific Publications), vol 80, pps. 1-249, 2008 His scientific publications include a total of 56 articles as of 2013.

Some of Shannahoff-Khalsa's most-cited work is a 1999 randomized control study on the effects of two meditation protocols on two groups of individuals with Obsessive-compulsive disorder (OCD).  The one group practiced The Relaxation Response plus Mindfulness Meditation technique, while the other group employed a Kundalini Yoga protocol specific for treating OCD.  After three months, it was found the Kundalini Yoga group showed greater improvement on all six scales, namely the Yale-Brown Obsessive-Compulsive Scale Y-BOCS, Symptoms Checklist-90-Revised Obsessive Compulsive (SC-90-R OC) and Global Severity Index (SC-90-R GSI), Profile of Moods Scale (POMS), Perceived Stress Scale (PSS), and Purpose in Life test (PiL).  Within group statistics (Student's paired t-tests) showed that the Kundalini Yoga group significantly improved on all six scales, while The Relaxation Response/Mindfulness Meditation group had no significant improvements on any scale. The groups were merged for an additional 12months using the Kundalini Yoga protocol, and final group improved significantly on all the scales, demonstrating that kundalini yoga techniques are effective in the treatment of OCD.

In 1993 he started work using magnetoencephalography (MEG) to study the brain effects of the yogic breathing technique specific for treating OCD using instrumentation at The Scripps Research Institute. That work continues today with collaborators at the University of Catania, Sicily. He continues to study the ultradian rhythm of alternating cerebral hemispheric activity using whole-head 306 MEG + 66 channel EEG and its coupling to the sleep stages of REM and NREM sleep with collaborators at UCSD and Harvard MGH.

In a 2006 editorial for The Journal of Complementary and Alternative Medicine, Shannahoff-Khalsa makes a case for the vigorous and rigorous - "using all possible blinding for assessment" - study of new treatment modalities for psychiatric disorders.
