Jennifer Elizabeth Cohn

Jennifer Elizabeth Cohn, MD, MPH is a Clinical Associate Professor in the Department of Infectious Diseases at the Perlman School of Medicine, University of Pennsylvania. She is a globally recognized expert in infectious diseases and access to health products, with extensive field experience in India, Kenya, South Africa, Brazil, and Switzerland. Her work bridges clinical medicine, public health policy, and global health innovation.

Her research focuses on antimicrobial resistance, HIV/AIDS, tuberculosis (especially pediatric TB), access to medicines, and health system innovation. She has led large-scale, multi-country implementation projects that have directly informed World Health Organization (WHO) guidelines and national health policies. Her expertise includes operational research, cost-effectiveness analysis, and the development of evidence-based interventions for low- and middle-income countries.

The most recent publications reflect a consistent trend in improving early diagnosis and treatment access for HIV and TB in children, optimizing antibiotic use in the face of rising resistance, and strengthening diagnostic and supply systems. Her work combines clinical insight with systems-level innovation, particularly in decentralized care models and community-based interventions.

Jennifer has served in key leadership roles, including Director of Global Access at the Global Antibiotic Research and Development Partnership (GARDP), Senior Director of Innovation at the Elizabeth Glaser Pediatric AIDS Foundation, and Medical Coordinator for the Doctors Without Borders (MSF) Access Campaign. She has advised WHO, PAHO, and national governments on TB, HIV, and AMR.

She has published over 90 peer-reviewed articles in high-impact journals such as The Lancet, Clinical Microbiology and Infection, and Pediatric Infectious Disease Journal. Her leadership in multi-country studies demonstrates active mentorship and collaboration, though specific student names are not listed. She works closely with academic medical centers, ministries of health, and civil society organizations to address evidence gaps and support the introduction of new health technologies.
