Research

My research focuses on moral and political questions about equality, migration, citizenship, and democracy. Much of my work explores the nature and value of equality, and traces the implications of taking equality seriously for contemporary political debates. I haved argued that a commitment to equality supports more open borders and I have developed an egalitarian theory of citizenship designed to inform debates about citizenship policy. Recently, I have been writing about the threats facing contemporary democracies, such as extreme political polarization and surging far-right populism, and how citizens should respond to them.
