Verified identity


I have been editing since 2015. Three years ago, I transitioned from editing news articles to editing trade and scholarly books. I have edited for a major metropolitan daily newspaper and an established university press, and I have also interned full-time at a Big Five publisher.

I am a 2018 graduate of the Columbia Publishing Course in New York, where I spent six weeks immersed in lectures and workshops related to all aspects of book, magazine, and digital media publishing. I hold both a bachelor of science in journalism with highest honors and a master of science in library and information science from the University of Illinois at Urbana-Champaign.

In 2017, I was one of eighty-five college students selected nationwide (out of 750 applicants) for the Dow Jones News Fund summer internship program. Before starting my copy editing internship at the Houston Chronicle, I went through a rigorous ten-day training at the Center for Editing Excellence at the University of Texas at Austin.

I enjoy editing non-fiction, especially books about arts, entertainment, culture, history, and women's studies. I welcome projects that include text in Romance languages, as I am fluent in Portuguese and proficient in French. I am always thrilled to edit books about my native country of Brazil.

Because of my journalism background, I am a thorough editor, fact checker, and researcher who can work under tight deadlines. I have worked with the AP Stylebook, the Chicago Manual of Style (17th ed.), and Merriam-Webster's Collegiate Dictionary (11th ed.).
