Drawing upon a range of critical theories, including feminist, postcolonial and queer theories, Anne Macduff's research explores how law devalues difference.

She has a particular interest in exploring issues of law and identity, including race, gender and sexuality. For instance, Anne's PhD thesis challenges the claim that Australian citizenship law is neutral and inclusive, and argues that the current laws construct a particular racialized and gendered citizen subject. Anne's interest in critically examining the way law excludes certain identities includes other areas of law, including tenancy, public law and family law.

Anne's research also explores the way that legal education devalues difference. Anne has published on critical thinking, reflection (with Marlene Le Brun) and portfolios (with Dr Chris Trevitt). She has also published on student workload (with Lynn Du Moulin).
