In 2015, Dr. Tu Nguyen earned her Doctor of Medicine degree from the University of Medicine and Pharmacy Ho Chi Minh City. Motivated by the conviction that high-quality education is a fundamental right, not merely a privilege, she embarked on a journey in the United States for residency training. Commencing in early 2016, she undertook the USMLE exams, achieving ECFMG certification in 2017.

Dr. Tu Nguyen successfully completed a 3-year Internal Medicine residency at Weiss Memorial Hospital, affiliated with the University of Illinois Chicago, in 2022. Subsequently, she pursued a 1-year Sleep Medicine fellowship at the University of Illinois Chicago in 2023.

Throughout her training, Dr. Tu Nguyen actively participated in hospital quality improvement projects. Her notable contributions earned her a state-level American College of Physician QI project award for her initiative, “Improving the Use of Dexamethasone in Hospitalized COVID Patients.” Additionally, she received national recognition by winning the 2022 ACP Quality Improvement Residency Program award at the ACP Advance Quality Improvement program, significantly enhancing the profile of the educational program at Weiss Hospital.
Beyond her clinical achievements, Dr. Tu Nguyen is a dedicated educator, mentoring junior colleagues, medical students, and patients alike.

Furthermore, Dr. Nguyen is deeply committed to Sleep Medicine, recognizing its novelty in Vietnam. Understanding the importance of sleep for daily life, she aspires to educate healthcare providers about the diagnosis and treatment of sleep disorders. Driven by a desire to improve the quality of life for Vietnamese patients, she aims to contribute to the advancement of Sleep Medicine in her home country.
