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, Contract Law And Contract Practice: Bridging The Gap Between Legal Reasoning And Commercial Expectation, was published by Hart in 2013. Previously published work includes a book, Interpretation of Contracts (Routledge Cavendish, 2007), as well as articles and short papers on exclusion clauses, third party rights, restitutionary damages and entire agreement clauses in contracts. She is currently working on a second edition of Interpretation of Contracts (Routledge) which is due to be published in 2017. She is also involved in projects examining networks and contract law, and the law relating to behavioural obligations in contracts.
