Christian's research interests are in the philosophy of mind, phenomenology of perception, naturalized epistemology, Buddhist philosophy, Hellenistic philosophy and cross-cultural hermeneutics. He is the author of Perceiving Reality: Consciousness, Intentionality, and Cognition in Buddhist Philosophy (OUP, 2012) (available also through Oxford Scholarship Online; reviewed in Mind and here). The central idea of this book is that perception should be understood as a practical engagement with the objects, situations and events of our lives, and thus as something that we do rather than something that happens to us. The book offers a sustained argument that Buddhist philosophers, in particular those who follow the tradition of inquiry initiated by Dignāga and Dharmakīrti, have much to contribute to current debates about perceptual consciousness, attention, self-awareness, and intentionality. He is currently working on his second book on a reflexive theory of perceptual awareness, tentatively titled The Reflexive Gaze: Phenomenology and Buddhist Philosophy of Mind.
