Maximillian is a political theorist working on questions of democracy and legitimacy in global governance. His research examines how consequential political decisions with cross-national effects can legitimately be made by international organisations, states, and non-state organisations. In doing so he engages with both analytical political theory and non-Western traditions of thought. 

In addition to teaching on LSE100, he teaches in the department of Government at LSE, and is an Associate Lecturer at Birkbeck, University of London.
