Dr Pui-Him Ip is Tutorial Programme Director and Research Associate at The Faraday Institute for Science and Religion. He is Programme Director for Tutorial Courses in Science and Religion at the Faraday Institute, which are run in partnership with universities around the world, including Hong Kong University, Hong Kong Baptist University and Baylor University in the USA.

Pui studied for a MSci in Theoretical Physics at Imperial College London before completing an MA in Philosophy and Christian Theology at Heythrop College, University of London and a PhD in Early Christian Theology at the Faculty of Divinity, University of Cambridge under the supervision of Prof. Rowan Williams. From 2018-2019, Pui was Departmental Lecturer in Patristics at the Faculty of Theology and Religion, University of Oxford, and Tutor in Theology at Christ Church, Oxford. Since joining the Faraday in 2019, he has been an Affiliated Lecturer in the Faculty of Divinity and a Research Associate at St Edmund’s College, University of Cambridge.

Pui’s research lies at the intersection between Patristics (Christianity in Late Antiquity) and Modern Christian Thought, inspired by the project of ressourcement theology initiated by 20th century figures such as Henri de Lubac, Hans Urs von Balthasar, and Jean Daniélou. His first book analysed the early Christian doctrine of divine simplicity in order to address contemporary debates about the nature of God. Much of his current work focuses on the thought and intellectual legacy of the Alexandrian exegete and philosopher Origen (c.185-c.253). He is currently working on a monograph examining in detail the tradition of reading the Book of Ecclesiastes as natural philosophy (physics) – an approach that originated with Origen’s Commentary on the Song of Songs. This research seeks to uncover why early Christians working in this tradition considered knowledge of nature (physics) as integral for shaping humans to become more virtuous and spiritual beings.

Pui is originally from Hong Kong but he has lived in the United Kingdom since 2002.
