Mark Siderits' research interests lie in the intersection between classical Indian philosophy on the one hand, and analytic metaphysics and philosophy of language on the other. He received his PhD from Yale University, and taught first at Illinois State University and then at Seoul National University, retiring from the latter in 2012. Among his more recent publications are Buddhism As Philosophy (Ashgate/Hackett, 2007), Personal Identity and Buddhist Philosophy: Empty Persons (Ashgate, 2nd revised edition 2015) and, together with Shôryû Katsura,Nâgârjuna's Middle Way: Mûlamadhyamakakârikâ (Wisdom, 2013). He has also edited several collections of work on Indian/analytic philosophy, including Self, No Self? (with Evan Thompson and Dan Zahavi OUP, 2010). Jan Westerhoff is Associate Professor of Religious Ethics at the University of Oxford, a Fellow and Tutor in Theology and Religion at Lady Margaret Hall, University of Oxford, and a Research Associate at the School of Oriental and African Studies, University of London.
