Currently I focus on Janina Hosiasson-Lindenbaum’s work in inductive logic and philosophy of probability, as well as her biography.

Before that, I worked on the history of Carnapian inductive logic. I wanted to situate inductive logic in the wider context of Carnap’s philosophy, as well as to systematically reconstruct it and the changes it went through, as a project in explication. This research was sponsored by the NWO under a Veni project “In Inductive Logic, There Are No Morals: Carnap’s Philosophy of Scientific Reasoning” (2020-2023).

My dissertation, “Inductive Logic on Conceptual Spaces”, was on modelling inductive reasoning using conceptual spaces. Conceptual spaces are a way to represent concepts via multi-dimensional, spatial structures, where meaning relations can be interpreted geometrically. I investigated the ways in which having such structured concepts in our linguistic/conceptual framework influences the way we make predictions based on observed data.
