Assistant Professor of Medicine

Carlos Mejia-Chew is an Assistant Professor in the Division of Infectious Disease and the Medical Director of the Outpatient Antimicrobial Therapy program. He specializes in mycobacterial infections, particularly nontuberculous mycobacterial (NTM) infections. 

Under the direction of ID division faculty, Dr. Carlos Mejia and Dr. Thomas Bailey, and Dr. Shail Mehta from Pulmonology, a pulmonary nontuberculous mycobacterial (NTM) disease clinic was established to see all patients with pulmonary NTM disease.  Through an integrated approach of multiple specialties (e.g. pulmonology, infectious disease, thoracic surgery, etc.) care is provided for patients with suspected, new, or refractory NTM disease. Clinical trials are available for patients in whom standard therapies have not been effective. Patients are also offered the opportunity to participate in additional scientific studies to further our understanding of this complex disease.

Dr. Mejia attends on the general, bone and joint, and telemedicine ID consult services teaching fellows, residents, and students; he sees patients in clinic, mainly those with NTM disease including extra-pulmonary NTM infections. He also collaborates with Dr. O’Halloran and Dr. Samayoa, from Roosevelt Hospital Guatemala, on a large cohort of people living with HIV, looking at multi-morbidity outcomes. As part of the Global Health Pathway he’s currently mentoring fellows, residents, and students in research.
