Scientific American appoints Mariette DiChristina Editor-in-Chief

Scientific American, the leading science magazine, today announces Mariette DiChristina as its new Editor-in-Chief. DiChristina becomes the eighth Editor-in-Chief in the 164-year history of the magazine, and the first woman to assume the role. In her role, DiChristina oversees the print and online editions of Scientific American and Scientific American Mind, as well as all newsstand special editions.

Mariette DiChristina is based in the Scientific American offices in New York City and takes up her position with immediate effect, reporting directly to Nature Publishing Group Managing Director Steven Inchcoombe. Announcing her appointment, Inchcoombe said "I am delighted to confirm Mariette as Editor-in-Chief of Scientific American. Mariette has always performed strongly and has been doing an especially great job over the last six months. She was the natural choice to lead Scientific American's editorial team and I look forward to working together with her to develop Scientific American to increase its impact and its value to its readers across all media."

DiChristina has been Acting Editor-in-Chief of Scientific American since June 2009, when outgoing Editor-in-Chief John Rennie left the publication to pursue new opportunities. A science journalist for more than 20 years, DiChristina first came to Scientific American in 2001 as its executive editor, a position she held until her current appointment. DiChristina also served as the editor of Scientific American Mind, a publication she launched, and started. Prior to joining Scientific American, DiChristina spent nearly 14 years at Popular Science in positions culminating as executive editor. DiChristina is the current president (in 2009 and 2010) of the 2,500-member National Association of Science Writers.

"Scientific American, at nearly 165, is as vital as ever as the world's premier source for advances in science and technology and how they shape our world. It is a privilege to help shepherd Scientific American's future," said DiChristina.

Described by The Chronicle of Higher Education as "probably the [United States'] most venerable source of science news written for a general audience", Scientific American delivers authoritative and thought-provoking content to more than 3 million readers worldwide. Founded in 1845, Scientific American has over its history published articles by more than 140 Nobel laureate authors including Albert Einstein, Francis Crick, Stanley Prusiner and Richard Axel. Scientific American became part of Nature Publishing Group (NPG) in 2009, after many years as a sister Holtzbrinck organization.

DiChristina's predecessor John Rennie was quick to congratulate her on her appointment: "Having worked side-by-side with Mariette for eight years, and having watched the great job she's done in recent months, I am more sure than ever that no one could be a better editor-in-chief for Scientific American. Mariette is a dynamic, brilliant editor and manager, and she will do terrifically well leading Scientific American forward and helping it thrive." Rennie serves as a Contributing Editor for Scientific American, and continues to edit and consult on features and news for the magazine.
