CV Frederik Heitmüller

Updated: 15 Jun 2026

I am an independent tax policy and research consultant. I am also an Associate Postdoctoral Fellow with the International Centre for Tax and Development (ICTD) and an guest lecturer at Leiden University. I completed a PhD in the GLOBTAXGOV Project at Leiden University in March 2024. My research focuses on policies against corporate tax avoidance, the influence of international norms in the Global South and tax policy for development. I work in an interdisciplinary way and I aim at contributing to the state of the art in political science and tax law scholarship.
