I spent early chapters of my working life as an academic, primarily in Canada and the UK, with research stays in Europe and the US. I published research articles, lectured, and organized conferences in a branch of scientific methodology. The bulk of this work focused on what justifies theories, and therefore on the nature of the relation between theory and evidence. This, in turn, is related to our understanding of the structure of theories and theory change. These interests, though motivated by a number of somewhat specialized debates, form part of a broader interest in the analysis and revision of our most basic scientific concepts.
Until recently, I retained an appointment as Associate Faculty at the University of Oxford, with whose staff I continue to enjoy intellectual exchange.
