Dr. Rochelle Walensky, who served as CDC director from 2021 to 2023, calls the job “probably the hardest thing I will ever do.” But she also calls it “the honor of a lifetime.” When she was appointed by President Biden as the CDC’s 19th director, she was already used to politicized health care issues, having spent her formative years as a physician working on HIV and AIDS. But COVID thrust her into an unprecedented spotlight, forcing her to lead a demoralized agency through the challenges of implementing policy and informing the public while navigating a highly polarized and often toxic public sphere and rapidly changing scientific data. Walensky says she learned some hard and valuable lessons during her tenure.  After stepping down from the post this summer, Walensky is now a senior fellow at the Women and Public Policy Program at Harvard Kennedy School, studying the topic of women’s leadership in the health care field. She is also exploring health care policy issues in concurrent fellowships at both Harvard Law School and Harvard Business School.

Dr. Rochelle Walensky is a renowned expert exploring the challenges and what it means for leaders, organizations, and the world to protect public health. Dr. Walensky was the chief of the Division of Infectious Diseases at Massachusetts General Hospital and served as the 19th director of the CDC and the ninth administrator of the Agency for Toxic Substances and Disease Registry. Having received an M.D. from the Johns Hopkins School of Medicine, she also trained in internal medicine and earned an MPH in clinical effectiveness from the Harvard School of Public Health in 2001. In the earliest part of the pandemic, Dr. Walensky served on the front lines, taking care of patients, serving on the Massachusetts General Hospital incident management team, and conducting research on vaccine delivery and strategies to reach underserved communities. Dr. Walensky’s tenure at the CDC began on January 20th, 2021, when she led the nation—and the world—through unprecedented times, facing the largest density of infectious threats likely ever seen in the United States. Dr. Walensky has also worked to improve HIV screening and care in South Africa, led health policy initiatives, and researched clinical trial design and evaluation in a variety of settings. She was chair of the Office of AIDS Research Advisory Council at the National Institutes of Health from 2014 to 2015. She has also been a member of the U.S. Department of Health and Human Services Panel on Antiretroviral Guidelines for Adults and Adolescents and served as co-director of the Medical Practice Evaluation Center at Massachusetts General Hospital since 2011 before assuming the position of CDC director.
