Mercedes Corina Becerra, S.c.D
Professor of Global Health and Social Medicine

Dr. Becerra's research focuses on the treatment and epidemiology of drug-resistant tuberculosis. She also studies the burden of tuberculosis in the child and adult household contacts of patients with drug-resistant tuberculosis and strategies to improve contact investigation, case detection, and treatment in high-risk households.
