Research Abstract
My research is focused on sleep, sleep disorders (especially sleep related breathing disorders and movement disorders), psychotropic drugs effect on sleep and wakefulness, sleep disorders affecting cardiovascular diseases and neuromuscular diseases. Below are the examples of research projects I have carried out and/or ongoing:
- Sleep related breathing disorders (SRBD) in medical ICU patients
- Sleep position preference in patients with untreated OSA versus non-OSA patients
- Prominent positional OSA in patients with stroke
- Periodic limb movement (PLM) in patients with leg paresis/plegia
- Role of serotonin in profound hypoxemia/hypoventilation
- PLM in patients taking serotonergic agents
- SRBD pattern in patients with neuromuscular disease
- Severe sleepiness in patients with myotonic dystrophy
- OSA in wake-up stroke
- Efficacy comparison of various sleep aids
- Effects of sleep aids on OSA
- Central sleep apnea pattern in acute stroke
- Patient characteristics in augmentation of restless legs syndrome (RLS)
- Effect of sleep intervention on neurocognitive outcomes of Alzheimer Disease patients
- Sleep related breathing disorders (SRBD) in medical ICU patients
- Sleep position preference in patients with untreated OSA versus non-OSA patients
- Prominent positional OSA in patients with stroke
- Periodic limb movement (PLM) in patients with leg paresis/plegia
- Role of serotonin in profound hypoxemia/hypoventilation
- PLM in patients taking serotonergic agents
- SRBD pattern in patients with neuromuscular disease
- Severe sleepiness in patients with myotonic dystrophy

Short Biography
Dr. Kevin Im graduated from Seoul National University College of Medicine in 1999. After one year of rotating internship and three years of rural health service in South Korea, he moved to the United States to start a residency training in combined internal medicine and psychiatry at the University of Iowa. During the med/psych training he was exposed to the field of sleep medicine by Dr. Eric Dyken, a pioneer of sleep research on sleep apnea’s linkage to sympathetic nerve and stroke. Dr. Im realized that sleep was the very overlapping field between med/ psych or body/ mind and can be a target of improving the wellness of both body and mind. He went on to be trained in neurology sleep medicine at the University of Iowa and remained there for 9 more years as a faculty in internal medicine, psychiatry, neurology and sleep medicine. In Iowa, he trained thirteen residents and fellows in sleep medicine, led many sleep research projects as principal investigator and produced more than thirty original research abstracts and articles, wrote more than 10 chapters on sleep medicine. He presented on the topics of sleep medicine and sleep disorders in more than 20 national and international venues. After the brand new, state-of-the-art sleep medicine center was established at UC Irvine in Newport Beach by the world renowned sleep medicine physician and researcher, Dr. Ruth Benca, Dr. Im ventured into the West Coast to join the dream team of sleep medicine at UC Irvine in the Fall of 2019. Dr. Im is triple board-certified in internal medicine, psychiatry and sleep medicine. His area of research and clinical interest encompasses all about sleep and sleep disorders including insomnias, sleep apneas, narcolepsy, restless legs syndrome, parasomnias and circadian rhythm.
