Amber Carpenter is associate professor at Yale-NUS. She has taught at the University of York, St Andrews, Cornell and Oxford. She publishes in ancient Greek philosophy, especially the ethics, epistemology and metaphysics of Plato. An Einstein Fellowship with the Einstein Forum (Berlin) enabled her to undertake work in Indian Buddhist philosophy. She held an anniversary lectureship from the University of York and was a visiting researcher at Melbourne. Her book on metaphysics as ethics in Indian Buddhism appeared in 2014. She is co-founder of the Yorkshire Ancient Philosophy Network (Yorkshire) and of the Ancient Worlds research group (Singapore). Her interests include the nature of pleasure and reason and their respective places in a well-lived life, the implications of metaphysics for ethics and the nature of knowledge, our striving for it, and the effects this has on our character. She will be pursuing topics related to this latter theme with a fellowship with The Beacon Project, exploring 'Ethical Ambitions and their Formation of Character' in Plato and in Buddhist thought. She coordinates, with Rachael Wiseman, the Integrity Project.
