My research interests are in the law of contract, the application of economic and social theories to law, and the theory and practice of regulation. My recent writings in these areas include Contractual Relations: A Contribution to the Critique of the Classical Law of Contract, Oxford, Oxford University Press, 2022; ‘Understanding Authoritarian Legality in Hong Kong: What Can Dicey and Rawls Tell Us?’, Weitseng Chen and Hualing Fu, eds, Authoritarian Legality in Asia: Formation, Development and Transition, Cambridge, Cambridge University Press, 2020, 143-68 (with R Cullen); and ‘The ‘Market’ in the Theory of Regulation’ (2018) 27 Social and Legal Studies 545-71.

Professor Campbell is happy to consider proposals in the area of the law of contract, the application of economic and social theories to law and the theory and practice of regulation.

My current teaching is largely in the law of contract, but I also teach issues in environmental regulation.
