I am Professor of History and Philosophy of Science at the National and Kapodistrian University of Athens. I received my PhD in history and philosophy of science from Princeton University. I have published on the history of modern physical sciences, and on meta-historical issues concerning conceptual change, scientific realism, scientific objects, and the integration of history and philosophy of science. I am the author of Representing Electrons: A Biographical Approach to Theoretical Entities (University of Chicago Press, 2006), co-editor of Kuhn’s The Structure of Scientific Revolutions Revisited (Routledge, 2012), and co-editor of Relocating the History of Science: Essays in Honor of Kostas Gavroglu (Springer, 2015). I have served as co-editor of the journal Metascience (2010-2014). In 2017 I was awarded the IUHPST Essay Prize in History and Philosophy of Science by the International Union of History and Philosophy of Science and Technology, for an essay entitled "What’s in it for the historian of science? Reflections on the value of philosophy of science for history of science".
