I am a Professor of Physics at the Institute for Quantum Information RWTH Aachen University. I hold an honorary position as a Visiting Reader at the Department of Computing Imperial College London.
Previously, I was a Senior Research Scientist at the Amazon Web Services Center for Quantum Computing and a Postdoctoral Researcher at the Institute for Quantum Information and Matter Caltech. I obtained my PhD degree from the Institute for Theoretical Physics at ETH Zurich.
The research in our group at RWTH Aachen is on mathematical questions in quantum information science, focusing on quantum communication theory, theoretical quantum cryptography, and the theory of quantum algorithms.
