Leo Martinez joined the Department of Epidemiology at Boston University in 2021. He completed his doctorate in epidemiology at the University of Georgia and a postdoctoral fellowship at Stanford University School of Medicine.
Dr. Martinez uses epidemiological and quantitative approaches to study early-life risk factors for pediatric tuberculosis in high-burden settings, tuberculosis transmission dynamics in high-risk populations (e.g., prisoners, persons living with HIV or diabetes), and the relationship between tuberculosis and non-communicable diseases.
Dr. Martinez's lab is currently working with colleagues and collaborators in South Africa, China, Brazil, Paraguay, Uganda, and the United Kingdom. We believe that collaboration across professional disciplines, backgrounds, and perspectives is the key to solving intractable health issues and the lab welcomes discussions with others working on these same health issues.
Dr. Martinez is an International Advisory Board member of the The Lancet Child & Adolescent Health and serves as an academic editor and Editorial Board member for two journals, PLOS Global Public Health and the Journal of Tuberculosis and Lung Disease.
Dr. Martinez has published manuscripts in clinical and epidemiological journals such as The Lancet, The Lancet Respiratory Medicine, The Lancet Global Health, The Lancet Child & Adolescent Health, The Lancet Public Health, the American Journal of Respiratory Care & Critical Medicine, the European Respiratory Journal, JAMA Internal Medicine, Clinical Infectious Diseases, the American Journal of Epidemiology, amongst others. A list of major publications is listed below but a full list can be seen in the publications tab on this profile page.
