Hi there! I am an Assistant Professor at the University of Illinois at Urbana-Champaign in the Department of Mathematics. I have recently been named a David Blackwell Scholar as well as a Lincoln Excellence for Assistant Professor (LEAP) Scholar. I'm also a member of IQUIST.

My research focuses on mathematical and information-theoretic aspects of quantum information theory. For more information you can explore this website, look at my short CV or full academic CV, and visit my research group website!

My research focuses on quantum information theory, in particular the mathematical and computational aspects of quantum Shannon theory. Below is a list of topics that I am particularly interested in, together with some selected papers. See the next section for a more detailed list of my recent papers.


Below is a list of my most recent papers, including both preprints and published articles. For a full list, see arXiv.org, Google Scholar, or my CV.

Before joining UIUC, I held postdoctoral positions at the Institute for Quantum Computing at the University of Waterloo and Perimeter Institute for Theoretical Physics from Dec 2019 to Dec 2020, and at JILA at the University of Colorado Boulder from Nov 2016 to Nov 2019. I obtained my PhD from the University of Cambridge in 2016 with a thesis on Relative entropies and their use in quantum information theory. My academic journey started in my hometown Vienna, Austria, where I obtained diploma degrees (≈ BSc + MSc) in Mathematics and Physics. Here is a link to my full academic CV.


I was born in Vienna, Austria. In my spare time I like to play the guitar, read, listen to music, play and watch (European) football, get better at cooking, and travel. Actually, I'm interested in pretty much everything.
