Rosanne Baars studied history at the University of Amsterdam (BA 2009, cum laude; RMA 2011, cum laude). In 2019 she obtained her PhD at the UvA with a dissertation on news exchange between the Netherlands and France in the sixteenth century (funded with a grant from the Dutch Research Council). Her book 'Rumours of Revolt' came out in May 2021 (Brill). She has a broad interest in the cultural history of the early modern period, especially in media and news reception. She has published on book ownership of seventeenth-century Amsterdam artists, eighteenth-century travel accounts, Dutch diplomacy with the Ottoman Empire and French propaganda in Aleppo in the Year of Disaster. She was a research fellow at the Netherlands Institute in Istanbul and Prof. J.C.M. Warnsinck fellow at the Maritime Museum in Amsterdam. In 2014 she published a book for a general audience on the travels of an eighteenth-century ship's surgeon to the Mediterranean and the Caribbean: 'Het Journaal van Joannes Veltkamp (1759-1764)' (WBooks, 2014). Her recent research focuses on the credibility of news in the early modern period and the role of women at the Dutch embassy in Istanbul around 1750.
