I am a Staff Research Scientist at IBM Research working on quantum computing and quantum information theory.

I obtained my PhD degree from the Institute for Theoretical Physics at ETH Zurich under the supervision of Renato Renner. My thesis can be found here.

I am the author of the book "Approximate Quantum Markov Chains" published by SpringerBriefs in Mathematical Physics
