Professor Degeling's research is about private law and its internal structures and architecture, and is premised on the view that private law should be transparent and rational. Her particular expertise lies in the law of unjust enrichment, the law of equity and the law of remedies. Within unjust enrichment scholarship, she has done extensive work on policy-motivated unjust factors and the intersections between unjust enrichment and tort. Professor Degeling uses both doctrinal and theoretical approaches to inform her work.
