I did my PhD in Philosophy at Stanford University with Peter Galison and Nancy Cartwright. My first academic position was at the University of California, Riverside. In 1998 I moved to the London School of Economics to join the department of Philosophy, Logic and Scientific Method. From 2002-2013 I was an ICREA at the UAB philosophy department. From 2005-2013 I was coordinator of the research group GRECC at the UAB. From 2009 - 2017 I was the founding Editor in Chief of the European Journal for Philosophy of Science, published by Springer. After a two-year sojourn in Canada (2013-2015) I returned to ICREA and joined the University of Barcelona and the LOGOS research group in July 2015. I am currently Scientific Director of the Barcelona Institute of Analytic Philosophy (BIAP), and IP of BIAP's María de Maeztu Unit of Excellence funding for 2023-2026. My monograph Chance in the World (OUP, 2019) won the Lakatos Award of the LSE in 2024.

My research has mostly addressed traditional metaphysical questions by examining the metaphysics of nature that flows from our best scientific theories. In particular, I have worked on the nature of space, time and motion as revealed by physics; and on the nature of objective probability as revealed by its uses in many branches of science and other human activities. My recent research interests include these topics: explanations provided by Einstein's relativity theories; scientific realism (i.e., should we take our best scientific theories to be giving us objective truth about the world?); and how to understand quantum non-locality. Stimulated by the Covid-19 pandemic responses, I have also worked on problems of causal inference in epidemiology and public health.
