Technology expands access. Longitudinal relationships are what change outcomes.
A community-based physician in sleep medicine and otolaryngology, and a digital-health researcher in Seoul — now building toward the next chapter of that work in the United States.
For over a decade I built a community sleep and ENT practice from the ground up. A precise diagnosis, I learned, means little without someone to carry it forward — to follow up, adjust, and stay with the patient across years.
Sleep apnea, weight, blood pressure, mood, adherence — none of these resolve in a single visit. That belief has run through every part of my career, and it is the thread I am following as I move toward comprehensive, longitudinal care in the United States.
Rotating internship followed by full specialty residency and Korean board certification — the clinical foundation.
Asking how diagnostics can reach more people. Published in The Lancet Digital Health, Scientific Reports, JMIR, and the International Journal of Cardiology; author of a general-audience book on medical AI.
Continued ENT clinical care while leading medical R&D — turning research into products, building new healthcare ventures, and putting clinical AI into practice.
Led an AI sleep-apnea diagnostic to Korean MFDS Class 2 clearance with Innovative Medical Device designation — turning research into a tool clinicians can use.
A community sleep and ENT practice delivering longitudinal, English-language care to an international patient population.
Hundreds of VA Compensation & Pension examinations to U.S. protocols — U.S. medical records, U.S. documentation standards, U.S. clinical expectations.
Bringing this work into comprehensive, whole-person primary care in an American community.
Diagnosis through management — CPAP and APAP titration, oral appliance therapy, and behavioral intervention. More than 2,794 polysomnography studies interpreted to AASM standards, as a member of the American Academy of Sleep Medicine.
The hard part of sleep medicine isn't the diagnosis — it's keeping patients in care. I build structured follow-up and patient-education workflows designed to sustain CPAP adherence and symptom tracking over years, not visits.
Led an AI sleep-apnea diagnostic to regulatory clearance, validated consumer sleep trackers against clinical polysomnography, and am named inventor on nine registered patents in sleep and health technology — technology that extends access without standing in for the clinician.
Years of U.S. veteran disability evaluations to VA protocols, with English-language documentation, prior authorization, and appeals to CPT and ICD-10 standards — fluency in how American care is documented and reimbursed.
Each of these is a way of asking the same question: how do you keep a patient in care long enough for the medicine to matter?
My research keeps returning to one question: how do you make diagnostics trustworthy and accessible enough to belong in everyday, ambulatory care?
