Assistant Professor
Dr. Jeffrey Tornheim
Jeff Tornheim, MD, MPH, is Assistant Professor in the Division of Infectious Diseases here at Johns Hopkins University School of Medicine. His research explores the application of new diagnostic technologies to improved health outcomes in the treatment of drug resistant tuberculosis among both adult and pediatric patients in India. 

Dr. Tornheim recently completed his infectious diseases fellowship at Johns Hopkins, during which he worked with Drs. Amita Gupta, Vidya Mave, Bob Bollinger of Johns Hopkins, and with Dr. Zarir Udwadia at the Hinduja Hospital in Mumbai. His interest in clinical outcomes for underserved populations led him to practice in physician training environments in Bolivia, Peru, South Sudan, Kenya, Uganda, Rwanda, South Africa, and the United States.

Dr. Tornheim completed a clinical fellowship in infectious diseases in June 2017. Prior to that he completed residencies at Yale University in both internal medicine and pediatrics. He received an MD/MPH from Mount Sinai School of Medicine, with his thesis evaluating the impact of water policy on rates of pediatric diarrhea in Bolivia. After completing undergraduate studies in International Development and Economics at Brandeis University he moved to East Africa where he engaged in health system strengthening for returning refugees to South Sudan and worked with the Centers for Disease Control and Prevention (CDC) on the epidemiology of pneumonia and diarrhea in Western Kenya. At the same time he worked at the Bureau of TB Control for the Department of Health and Mental Hygiene and was actively engaged in the operations of an East Harlem free clinic. As a Fogarty International Clinical Scholar, he spent 2 years in rural Bolivia establishing and managing operations for a Chagas Disease treatment program.
