I research in private law doctrine, and its philosophy. So far this has largely been in contract and unjust enrichment, but increasingly it has extended to torts. I am particularly interested in private law's remedial aspects, and this is reflected in the questions I have sought answers to during my doctoral research.

Previously I obtained my LLB (2014) from the National University of Singapore (NUS) as top first, where I assumed my first appointment as an inaugural Sheridan Fellow. I came to Oxford as a Clarendon Scholar, reading for the BCL (2016, dist), then writing an MPhil (2017) and DPhil (2020) on Standing in Private Law under the co-supervision of Professors Robert Stevens and Sandy Steel. I was Stipendiary Lecturer in Law at Merton college, and taught Commercial Remedies on the BCL. In August 2020 I will commence a post at the NUS Faculty of Law, and can be contacted at
