Principal Investigator

As one of the few academic sleep surgeons in the nation with active grant funding for sleep apnea research, Dr. Yi Cai focuses her research on the health outcomes of patients undergoing obstructive sleep apnea (OSA) treatments and optimizing care delivery for these patients.

Currently, Dr. Cai’s research on the cardiometabolic outcomes of OSA surgery is funded by the American Academy of Sleep Medicine Foundation, Triological Society (a national otolaryngology society), and the American Heart Association. In addition, ongoing projects in her lab investigate cardiometabolic health among patients with OSA and the use of wearable technologies to enhance care in OSA.

Dr. Cai has mentored several medical trainees on prior research projects and is accepting applications for summer and research year fellowships at otosleepresearch@cumc.columbia.edu
