Mariette DiChristina

Mariette DiChristina is an American science journalist and academic administrator. She is dean of the Boston University College of Communication, where she is also a professor of journalism. She was editor-in-chief of Scientific American from December 2009 to September 2019, becoming the first woman to hold that role since its founding in 1845. She was executive vice president of Springer Nature, overseeing the editorial and publishing operations of Scientific American and Nature with more than 160 staff members in ten countries.

DiChristina is a Fellow of the American Association for the Advancement of Science (AAAS) and has been on advisory bodies including the World Economic Forum's "Top 10 Emerging Technologies" steering group and the United States National Academies of Sciences, Engineering, and Medicine. Though she considered a career in astronomy, she turned toward writing and journalism instead. She attended Boston University, majoring in journalism at what is now the Boston University College of Communication, and graduated in 1986. Her coverage of space exploration, including the Hubble Space Telescope and extrasolar planets, helped the magazine win the Space Foundation's Douglas S. Morrow Public Outreach Award in 2001. She was the eighth editor-in-chief in the magazine's history and the first woman to hold the post. Digital traffic to the magazine's website grew by more than 500 percent during her tenure.

In 2015, DiChristina took on the additional role of executive vice president at Springer Nature, overseeing a staff of more than 160 people across ten countries and managing the Scientific American and Nature brands. Lee wrote a response to the email and posted it on the Scientific American blog. Then editor-in-chief DiChristina removed Lee's post, citing legal reasons: "Unfortunately, we could not quickly verify the facts of the blog post and consequently for legal reasons we had to remove the post," she said. She later told BuzzFeed the post was also outside the remit of the blog, which is to post information on science topics, and "verged into the personal." Numerous media outlets viewed Scientific Americans actions as censorship. A number of people posted on Twitter with support for Lee, under the hashtags #standingwithDNLee and #BoycottSciAm.

Boston University (2019–present) DiChristina returned to her alma mater in August 2019 as dean of the Boston University College of Communication, succeeding two-time Pulitzer Prize winner Thomas Fiedler. She has more than 80 full-time faculty, over 100 part-time instructors, 45 staff, and approximately 2,600 students under her in journalism, advertising, film and television, communication, emerging media, and public relations programs.

DiChristina led the college to establish the Center for Media Innovation & Social Impact (MISI), backed by $2.25 million in funding from the College of Communications and additional funding from the Feld Family Initiative for Civic Science Communication. The center uses the services of faculty across the College of Communications' departments and offers fellowships to community partners, with a focus on strengthening local news and using science communication to help with various problems. The college also launched The Newsroom, a course connecting student journalists with local news outlets across eastern Massachusetts. During its first full year of operation, 64 student reporters published over 300 articles across 31 local news organizations.

On September 7, 2022, Brian McGrory announced he would step down as editor of The Boston Globe at the end of the year to become chair of Boston University's journalism department. In 2018, former Globe editor Hilary Sargent accused McGrory of sexual harassment while he was overseeing her work. McGrory denied the allegation, and an internal investigation cleared him of wrongdoing. In a statement to BU Today, DiChristina praised McGrory's leadership and vision. “In a world where journalism is both more vital than ever and also more challenged, Brian has provided exceptional leadership at one of the most respected journalistic enterprises in the nation,” DiChristina said. “He brings high standards, an innovative approach to newsrooms going through change, and a deep commitment to diversity, equity, and inclusion.”

Other roles and affiliations DiChristina chairs the steering group for the World Economic Forum's "Top 10 Emerging Technologies" annual report. She joined the Rita Allen Foundation board of directors in 2024.

In July 2014, she testified before the United States Senate Committee on Commerce, Science, and Transportation at a hearing on federal research and development investment. In the hearing she argued for sustained government funding of basic scientific research. DiChristina was president of the National Association of Science Writers in 2009 and 2010, when the organization had approximately 2,500 members. She previously chaired Science Writers in New York (2001–2004) and was an adjunct professor in the graduate Science, Health and Environmental Reporting program at New York University's Arthur L. Carter Journalism Institute. showed that DiChristina and Epstein made plans for an in-person meeting in Manhattan in July 2014 and scheduled phone calls. DiChristina also asked Epstein to attend an editorial meeting at Scientific American. All of this communication occurred after Epstein had pleaded guilty in 2008 to soliciting a minor for prostitution and registered as a sex offender, which received a lot of press coverage at the time.

The information led to criticism from faculty and students at the College of Communication. The College of Communication's Student Government cancelled DiChristina's invitation to its spring semester town hall and released a statement requesting her to address the email correspondence that was uncovered.

On March 31, 2026, DiChristina addressed students directly, apologizing for not speaking sooner. She said the delay was due to work travel, spring break, and underestimating "how upsetting it was for some people". She added: "I can't help what happened in the past. I really wish I knew then what everybody learned in 2019 that I didn't know then myself."

Zelnick lawsuit In March 2026, The Daily Free Press reported that Marni Zelnick, a former professor at the Boston University College of Communication, had filed a lawsuit in federal court against the university seeking $1.6 million in damages. Zelnick alleged she experienced gender discrimination and retaliation from DiChristina's office between 2022 and 2025.
