Marvin is a research associate at the Centre for Social Critique at Humboldt University in Berlin. In his dissertation entitled “Narcissism and Ideology,” he develops a social-philosophical-psychoanalytical theory of regressive politics as a social-structurally induced crisis of social freedom, following Karl Marx, Sigmund Freud, Michael Bálint, Cornelius Castoriadis, and Theodor W. Adorno.
