Matthias Troyer is a Principal Researcher in the Quantum Group of Microsoft. After receiving his PhD in 1994 from ETH Zurich, he spent time as a postdoc at the University of Tokyo before returning to ETH Zurich. There he has been a professor of Computational Physics until taking leave of absence to join Microsoft’s quantum computing program at the beginning of 2017. Matthias is a Fellow of the American Physical Society, a Trustee of the Aspen Center for Physics, and a recipient of the Rahman Prize for Computational Physics of the American Physical Society. His research interests span from high performance computing and library design for scientific computing to the simulations of quantum devices and island ecosystems. At Microsoft he now works on various aspects of quantum computing, from numerical modeling of quantum hardware to discovering new applications for quantum computers.
