I spent early chapters of 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 on the structure of physical theories. This work, though motivated by a number of somewhat specialized debates in the foundations of physics, forms part of a broader interest in the analysis and revision of our most basic scientific concepts.
All of this work lies within the broad field of scientific methodology, roughly, the study of what is methodologically rational about the sciences. Those who work in this field are interested in what justifies theories, and therefore in the nature of the relation between theory and evidence.
Until recently, I retained an appointment as Associate Faculty at the University of Oxford, with whose staff I continue to enjoy intellectual exchange.
