Junjie Liu


Dr. Liu received Ph.D. in applied physics and electrical engineering, and conducted years of research in the brain imaging of both humans and small animals, before he studied medicine and completed clinical training in both internal medicine and sleep medicine. Starting in July 2019, Dr. Liu will return to the research arena, and will focus on obstructive sleep apnea (OSA), a very common yet often ignored disease that impacts more than 20 million Americans. Drawing on his prior expertise in brain imaging, Dr. Liu proposed to study the brain activity during sleep in OSA patients by using functional magnetic resonance imaging (fMRI), a rapid whole-brain imaging method. Luckily, this proposed study is now in progress, thanks to the kind support (Focused Projects Award) from the American Academy of Sleep Medicine. In addition, Dr. Liu is very interested in the interactions between OSA and two common diseases, namely the chronic kidney disease (CKD) and stroke. He is contributing to the pertinent clinical studies in renal function and stroke led by his primary mentor, Dr. H. Klar Yaggi. These ongoing projects will help Dr. Liu develop his patient-oriented research career in sleep medicine.
