I am a philosopher of science, primarily of biology, working at the University of Toronto. I received a PhD in evolutionary biology from McGill University in Montreal, and a PhD in Philosophy from Kings College London. Over the years I have worked extensively on the nature of explanation in biology. I formulated and defended what became known as the „statistical interpretation“ of population dynamics models. I have worked extensively on the understanding of naturalised teleology and its role in evolutionary biology. Since 2012, I have been researching the concept of agency as it applies to evolutionary biology. In particular, I have articulated and defended the „ecological account“ of agency. In 2015 I published Organisms, Agency, and Evolution (Cambridge University Press), (a significant part of which was written while on various visits to KLI). In 2018-2019 I was fellow at the Institute for Advance Study, Paris (and FMSH). I have taught at LSE, University of Edinburgh, Dartmouth College, MIT, and University of Toronto.
