Biography

Mohammed T. Numan, MD, is a professor of pediatrics in the Division of Pediatric Cardiology at McGovern Medical School at UTHealth Houston and serves as director of pediatric electrophysiology and director of the Dysautonomia Center of Excellence at the Children’s Heart Institute. Internationally recognized for his expertise in pediatric cardiac electrophysiology, autonomic disorders, and congenital heart disease, Dr. Numan has dedicated more than two decades to advancing patient care, education, and research in these specialized fields.

Dr. Numan earned his medical degree from King Faisal University in Saudi Arabia and completed residency training in pediatrics in both Saudi Arabia and the United States. He subsequently completed fellowships in neonatology and perinatal medicine, pediatric cardiology, and pediatric cardiac electrophysiology, culminating in advanced subspecialty training at the Medical University of South Carolina.

Before joining UTHealth Houston in 2009, Dr. Numan held numerous academic and leadership appointments in Qatar, including director of pediatric cardiology, director of cardiac electrophysiology, and pediatric residency program director at Hamad Hospital. At UTHealth Houston, he has served as interim director of the Division of Pediatric Cardiology and chair of the Pediatric Cardiology Fellowship Clinical Competency Committee, helping shape the development of future pediatric cardiologists. A pioneer in the field of pediatric dysautonomia, Dr. Numan co-founded the Pediatric Dysautonomia Center at Memorial Hermann Hospital in 2011, creating one of the nation’s leading multidisciplinary programs for children and adolescents with autonomic nervous system disorders. His work has significantly advanced understanding of postural orthostatic tachycardia syndrome (POTS), neurocardiogenic syncope, orthostatic intolerance, and related autonomic conditions. He has also played a key role in developing national guidelines and consensus statements through the American Autonomic Society, where he served as chairman of the pediatric section and a member of the board of directors.

Dr. Numan’s clinical expertise includes catheter ablation, pacemaker and implantable cardioverter-defibrillator management, congenital electrophysiology procedures, tilt-table testing, autonomic function assessment, and the diagnosis and treatment of complex arrhythmias in children and adults with congenital heart disease. Under his leadership, the Pediatric Electrophysiology Program at UTHealth Houston has grown into a high-volume regional referral center.

An accomplished researcher, educator, and mentor, Dr. Numan has authored more than 100 peer-reviewed publications, abstracts, book chapters, and scientific presentations. His contributions to pediatric electrophysiology and autonomic medicine have earned national recognition, including the McGovern Medical School Dean’s Teaching Excellence Award, election to the Board of Directors of the American Autonomic Society, designation as a Fellow of the Heart Rhythm Society (FHRS), and Fellow of the American Autonomic Society (FAAS). He has also been repeatedly recognized as one of Houston’s Top Doctors by his peers.
Through his commitment to innovation, clinical excellence, and education, Dr. Numan continues to advance the diagnosis and treatment of pediatric heart rhythm disorders and autonomic diseases while mentoring the next generation of leaders in pediatric cardiology and electrophysiology.
