Catherine's research interests lie primarily within the field of the private law of obligations. In particular all aspects of contract law including nature and theory of contractual obligations, remedies, consumer and commercial contracts, and the relationship between contract, tort and restitution. She is also interested in legal theory, particularly legal reasoning, interpretation in law and law and literature.
Her most recent monograph, a second edition of Interpretation of Contracts (Routledge), was published in 2018. Previous works include Contract Law And Contract Practice: Bridging The Gap Between Legal Reasoning And Commercial Expectation (Hart 2013) and the first edition of Interpretation of Contracts (Routledge Cavendish 2007). She has published articles and short papers on a variety of contract issues: exclusion clauses, third party rights, restitutionary damages, entire agreement clauses, networks and contract law, and the law relating to behavioural obligations in contracts.
Her current project - Vanishing Contract Law - is supported by a Research Fellowship from the Leverhulme Trust. A monograph arising from the project will be published by Cambridge University Press in 2022.
