She has been a part of the History of Science & Knowledge Research Group in Turku since 2013.

Penttinen's research focuses on the ways mid-seventeenth-century English public collections embodied European geographical imaginations, enabling people from different backgrounds to experience the world virtually. She is particularly interested in the intersections of knowledge, travel, and material culture in the early modern period, with a focus on geographical imaginations and the histories of virtuality and virtual travel.
