Dr Catterwell is the author of a book titled “A Unified Approach to Contract Interpretation” published by Hart Publishing. He holds a PhD in contract interpretation from the University of Sydney. He is published on contract law in leading Australian and English journals.

Dr Catterwell’s research interests include private law, commercial law, contract theory, legal interpretation, logic and law, and law and technology. In broad terms, his research seeks to explain the law by employing a blend of theoretical and empirical methods. Ryan also applies his doctrinal research in exploring the extent to which legal reasoning can be automated.
