I grew up in Vienna, Austria. After studying Mathematics and Physics at the University of Vienna from 2006-2013, I obtained my PhD in Mathematics from the University of Cambridge in 2017. I was a Postdoctoral Research Associate at JILA, University of Colorado Boulder from 2016-2019, and a Joint Postdoctoral Fellow at the Institute for Quantum Computing, University of Waterloo and the Perimeter Institute for Theoretical Physics from 2019-2020. In January 2021 I joined the Department of Mathematics at UIUC as an Assistant Professor. My research focuses on quantum information theory.

Research Interests

Mathematical and computational aspects of quantum information theory

Research Description

I study mathematical and computational aspects of quantum information theory. In particular, I am interested in the following topics:

  • Quantum channels and their various capacities
  • Additivity problems
  • Multipartite entanglement
  • Stabilizer formalism, in particular graph states
  • Teleportation protocols
  • Entropic quantities and their properties (see my PhD thesis)
  • Second order asymptotics
  • Classical and quantum network information theory

To study these topics, I use tools from representation theory and group theory, matrix analysis, convex optimization (in particular semidefinite programming), global optimization, and machine learning.


PhD, University of Cambridge, 2017
