Campos Seijo began her publishing career in the UK as a technical editor at the European Respiratory Society.[2] Her first Editor-in-Chief assignment came as head of a suite of pharmaceutical technology titles at Advanstar Communications, now part of UBM.[3] In 2009, she became Editor-in-Chief of Chemistry World, the monthly news magazine published by the Royal Society of Chemistry.[4] In 2014 she took on her current role at C&EN and moved to Washington, DC.[5]
Under Campos Seijo's leadership, C&EN has undergone a radical transformation, evolving into a modern media organization that is "home for ambitious journalism that reaches chemical scientists all over the world". C&EN's overhaul has resulted in new a complete revamp of the brand, including design, layout and user experience in print and online, as well as an editorial shift towards topical and global coverage.
This change has stimulated a greater focus on innovation and the development of a series of products aimed at supporting the digital expansion of the C&EN brand, including the implementation of a metered paywall, use of AI to drive its content recommendation engine or the launch of a voice skill for Amazon Echo devices.[6][7]
Other initiatives of note include the establishment of internationally recognized awards programs, including the Talented 12[8][9][10] and the Brazilian Women in Chemistry and Related Sciences Award sponsored by C&EN and CAS, as well as content sharing partnerships[11][12][13] for the distribution of C&EN content translated into Spanish, Chinese and Portuguese.
In 2017, Campos Seijo and her team at the ACS started a custom content studio aimed at serving the needs of chemical and pharmaceutical organizations inside C&EN, dubbed "C&EN BrandLab".[14]
This transformation has garnered the magazine several accolades, including EXCEL's Best Feature Article, Folio:'s Overall Editorial Excellence and Long Form Feature Content, and Connectiv's Innovation awards.[15][16][17]
To further the public image for chemistry, Campos Seijo presents at global scientific conferences as a publishing and outreach thought leader. She has appeared at the Conferencia Latino Americana de Quimica (CLAQ) in Havana, Cuba,[18] the World Conference of Science Journalists (WCSJ) in San Francisco, US,[19] and the European Chemical Society (EuChemS) conference in Liverpool, UK.[20] in addition to prominent roles at most ACS National Meetings.
She has also shown support of the European and International Young Chemists Networks, her activities in Latin America and through C&EN by organizing the first sexual harassment symposium at an ACS National meeting as well as collaborating with the Gordon Research Conferences to 1 bring their Power Hour to ACS members.
