Rochelle Paula Walensky (née Bersoff; born April 5, 1969) is an American physician-scientist who is the director of the Centers for Disease Control and Prevention and the administrator of the Agency for Toxic Substances and Disease Registry.[1] Prior to her appointment at the CDC, she was the Chief of the Division of Infectious Diseases at Massachusetts General Hospital and a professor of medicine at Harvard Medical School. Walensky is an expert on HIV/AIDS.[2]

Early life and education[edit]

Walensky was born Rochelle Paula Bersoff in Peabody, Massachusetts,[3] to Edward Bersoff and Carol Bersoff-Bernstein.[4] She was raised in Potomac, Maryland.[5][6]

In 1991, Walensky received a B.A. in biochemistry and molecular biology from Washington University in St. Louis.[6] In 1995, she received an M.D. from Johns Hopkins School of Medicine. From 1995 to 1998, she trained in internal medicine at Johns Hopkins Hospital. Walensky then became a fellow in the Massachusetts General Hospital/Brigham and Women's Hospital Infectious Diseases Fellowship Program. In 2001, she earned an MPH in clinical effectiveness from the Harvard School of Public Health.[7]

Academic career[edit]

Walensky had been on the faculty of Harvard Medical School since 2001, first as an instructor, then as a professor.[8] Walensky was a professor of medicine at Harvard Medical School from 2012 to 2020, and served as chief of the division of infectious diseases at Massachusetts General Hospital from 2017 to 2020. She conducted research on vaccine delivery and strategies to reach underserved communities. Walensky has 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.[9]

Walensky was chair of the Office of AIDS Research Advisory Council at the National Institutes of Health from 2014 to 2015 and has served as a member of the US Department of Health and Human Services Panel on Antiretroviral Guidelines for Adults and Adolescents since 2011.[10] She serves on the board of directors of Mass General Brigham.[11] She has been co-director of the Medical Practice Evaluation Center at Massachusetts General Hospital since 2011.[10]


In a paper published in Health Affairs in November 2020, Walensky and her co-authors showed that the effectiveness of a COVID-19 vaccine will be strongly affected by:

  • The speed with which the vaccine is produced and administered. Some of the potential vaccines have logistical challenges including the need for ultra-cold storage or requiring two doses.
  • The willingness of people to be vaccinated.
  • The pandemic's severity when the vaccine is introduced.[12]

CDC director[edit]

President-elect Joe Biden announced Walensky's presumptive appointment as CDC director on December 7, 2020, during the presidential transition.[13] Doctors and public health experts widely praised the choice.[14] As the position of director of the CDC does not require Senate confirmation to take office,[15] Walensky's tenure at the CDC began on January 20, 2021.

On August 3, 2021, Walensky instituted a 60-day extension of a federal COVID-related ban, which had just expired, on landlords evicting their tenants. The extended ban applied only to "counties experiencing substantial and high levels of community transmission levels", but under the criteria of the ban this covered an area holding 90% of the U.S. population.[16] On August 26, as was widely expected,[17] the U.S. Supreme Court struck down the extension as unconstitutional, ruling that only the U.S. Congress had the authority to issue such a moratorium.[18]

As the pandemic entered the Omicron variant wave, Walensky acknowledged that officials on the CDC response team were burned out,[19] and tried to reassign workers. Walensky and other top officials had a plan to dissolve large parts of the pandemic response team, which has more than 1,500 staffers, and reassign members to their original posts. Walensky shelved the plan with the emergence of Omicron as cases began to tick up across the U.S.,[19] bringing morale lower than ever at the CDC. However, Ashish Jha says, "Dr. Walensky inherited a really messy organization with some real strengths but also a lot of problems."[19]

In a January 18, 2022 interview with The Boston Globe Walensky responded to some of the criticisms of her first year in office.

Her critics told the Globe that she has confused the public on issues like quarantine guidance, school reopening, and mask-wearing. "What we’re seeing is policy failures, accompanied by poor messaging," said Anne N. Sosin, a public health researcher at Dartmouth College, who added that the rest of the administration is also to blame. Critics said that the CDC was prioritizing the economy over public health. The American Medical Association criticized her December 27 guidance to shorten the COVID isolation period from 10 to 5 days and to let people who contracted COVID leave isolation without a negative test.

Walensky described her critics as "naysayers" who have helped sow the public confusion she has been accused of creating and pointing out that many Americans are still not following the most basic guidance on COVID-19 prevention. She also said, "We’re making decisions in imperfect times, sometimes without all the data that we would like to make them.” Walensky said she is working with a messaging coach and she is listening to her critics. She said that better communication is not always possible. "Some of this is not based on the messaging because, 'Wear a mask' is about as crystal clear as you could be. And still we have much of America not doing it. So some of the really easy stuff is not being followed, and some of the harder stuff is actually complicated science."[20]

During a January 26, 2022 news conference about the rise of the Omicron variant and high hospitalization rates, Dr. Walensky said the nation should not ease up on COVID-19 safety protocols, saying, "Milder does not mean mild and we cannot look past the strain on our health systems and substantial number of deaths." She also said, "It's important to remember we're still facing a high overall burden of disease."[21]

Personal life[edit]

Walensky is married to Loren D. Walensky, also a physician-scientist. They have three sons.[22] They are Jewish and members of Temple Emanuel in Newton, Massachusetts.[23]
