Career

  • since 2016: Stephen Hawking Advanced Fellow / Senior Research Associate, DAMTP, University of Cambridge
  • 2013-2016: Postdoctoral Member, School of Natural Sciences, Institute for Advanced Study, Princeton, NJ
  • 2009-2013: PhD, University of Zurich

Research

Tobias is a member of the Department of Applied Mathematics and Theoretical Physics Relativity and Gravitation Group and the Center for Theoretical Cosmology. His research focuses on modelling the Large Scale Structure of the Universe and learning about the physics that shaped our Universe from current and upcoming galaxy surveys.

Teaching

In lent term 2018 I am teaching half of the Part III course on Advanced Cosmology. Lecture notes and exercises can be found here.
