Ennaliina Leiwo is a doctoral researcher in Finnish literature at the University of Turku. Her dissertation, based on extensive interviews with authors, editors, sensitivity readers, and marketing personnel of contemporary Finnish youth literature, investigates youth literature publishing in Finland in the 2020s.

The research focuses on issues of authorship and audience in contemporary Finnish youth literature publishing, as well as the potential of empirical methods in literary authorship studies. Of particular interest are the ideological landscape and institutional dynamics of the publishing field today, including approaches to racial diversity and racism, attitudes towards adult supremacy, and responses to rapidly changing linguistic dynamics, especially the dominance of the English language.

Alongside her research, Ennaliina has worked as a children's librarian at a public library, as well as a creative writing teacher in a project organized in collaboration with Girls' Houses across Finland and funded by the Finnish Cultural Foundation.
