As curator and historian, my research combines history of science and medicine with the study of material and visual culture. Whereas scholars are used to analyse objects still extant today, I also study those materials – such as blood and earwax – that have not been stored and saved. Although this poses challenges to the historian, I develop innovative methods to reconstruct and present past collections and think about the materiality of materials in the early modern period.
Blood, Sweat and Tears
Ruben's PhD project ‘Blood, Sweat and Tears’ (2013–2018) investigated how the chemistry of bodily fluids helped establish a new medical system in eighteenth-century Europe. Successfully defended in 2018, the dissertation "Fluid Bodies" argued that at the turn of the eighteenth century, the introduction of new chemical research methods and instruments crucially changed the perception of bodily fluids, which contributed to a new understanding of the human body and a new system of medicine.

Deafness in Transition
The aim of the 'Deafness in Transition' project (2019–2022) is to uncover cultural experiences and medical perceptions of deafness in early modern Europe. I focus on both social and medical perceptions of deafness, which includes both the profoundly deaf and those with hearing difficulty as the result of disease, accident, old age, or changing social and cultural requirements. This provides a new and more inclusive vintage-point to look at deaf history.
