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.

AI can be democracy’s ally—but not if it works for Big Tech
Kennedy School Lecturer in Public Policy Bruce Schneier says Artificial Intelligence has the potential to transform the democratic process in ways that could be good, bad, and potentially mind-boggling. The important thing, he says, will be to use regulation and other tools to make sure that AIs are working for us, and just not for Big Tech companies—a hard lesson we’ve already learned through our experience with social media. When ChatGPT and other generative AI tools were released to the public late last year, it was as if someone had opened the floodgates on a thousand urgent questions that just weeks before had mostly preoccupied academics, futurists, and science fiction writers. Now those questions are being asked by many of us—teachers, students, parents, politicians, bureaucrats, citizens, businesspeople, and workers. What can it do for us? What will it do to us? Will it take our jobs? How do we use it in a way that’s both ethical and legal? And will it help or hurt our already-distressed democracy? Schneier, a public interest technologist, cryptographer, and internationally-known internet security specialist whose newsletter and blog are read by a quarter million people, says that AI’s inexorable march into our lives and into our politics is likely to start with small changes, like AI helping write policy and legislation. The future, however, could hold possibilities that we have a hard time wrapping our current minds around—like AI entities creating political parties or autonomously fundraising and generating profits to back political candidates or causes. Overall, like a lot of other things. it’s likely to be a mixed bag of the good and the bad.
Bruce Schneier is a Lecturer in Public Policy at the Harvard Kennedy School, a faculty affiliate at the Ash Center for Democratic Governance and Innovation at HKS, a fellow at the Berkman-Klein Center for Internet and Society at Harvard University. An internationally renowned security technologist, he has been called a "security guru" by the Economist and is the New York Times best-selling author of 14 books—including A Hacker's Mind—as well as hundreds of articles, essays, and academic papers. His influential newsletter “Crypto-Gram” and blog “Schneier on Security” are read by over 250,000 people. Schneier is a board member of the Electronic Frontier Foundation and AccessNow, and an advisory board member of EPIC and VerifiedVoting.org. He is the Chief of Security Architecture at Inrupt, Inc.

How to keep "TLDR" syndrome from killing your policy proposal
Harvard Kennedy School Professor Todd Rogers and Lecturer in Public Policy Lauren Brodsky say trying too hard to sound intelligent—even when communicating complex or nuanced ideas—isn't a smart strategy. Because today’s overburdened information consumers are as much skimmers as readers, Rogers and Brodsky teach people how to put readers first and use tools like simplification, formatting, and storytelling for maximum engagement. They say you can have the most brilliant, well-researched ideas in the policy world, but you can’t communicate them, they’ll never reach the ultimate goal—making an impact. Rogers is the faculty chair of the Behavioral Insights Group at the Kennedy School and the author of “Writing for Busy Readers: The Science of Writing Better.” Brodsky is senior director of the HKS Communications Program and the author of “Because Data Can’t Speak for Itself,” a book about how to more effectively communicate the data that supports groundbreaking research and evidence-based policy proposals. They say snarky millennials may be to something when they dismissively mocked your wordy social posts and text messages by replying “TLDR”—"too long; didn’t read”—because that’s how many busy readers feel about a lot of the writing that researchers, academics, and policy wonks do.
Todd Rogers is a Professor of Public Policy at the Harvard Kennedy School of Government. He is a behavioral scientist who works to improve communication, increase student attendance, and strengthens democracy. At Harvard, he is the faculty director of the Behavioral Insights Group and faculty chair of the executive education program Behavioral Insights and Public Policy. He received a Ph.D. jointly from Harvard's department of Psychology and Harvard Business School, and received a B.A. from Williams College, majoring in both Religion and Psychology. He is also co-founded two social enterprises: the Analyst Institute which focuses on improving voter communications, and EveryDay Labs, which partners with school districts to reduce student absenteeism. He is the author of the book “Writing for Busy Readers: The Science of Writing Better.”
Lauren Brodsky is the senior director of the HKS Communications Program and a lecturer in public policy who teaches courses on policy writing and persuasive communications. She is also faculty chair of the executive education program “Persuasive Communication: Narrative, Evidence, Impact.” A co-author of the book “Because Data Can’t Speak for Itself,” she also publishes the website Policy Memo Resource (www.policymemos.hks.harvard.edu) at HKS. Lauren lectures widely on policy communications and the use of evidence in writing for governmental agencies and non-profit organizations. She is a former Theodore Sorensen Research Fellow at the John F. Kennedy Presidential Library and Museum, where she conducted archival research on public diplomacy programs during the Kennedy administration. She holds a B.A. from the University of Pennsylvania and an M.A.L.D. and Ph.D. from the Fletcher School at Tufts University.
