After receiving his PhD in 1994 from ETH Zurich in Switzerland he spent time as postdoc at the University of Tokyo before returning to ETH Zurich. There, he has been professor of Computational Physics until joining Microsoft’s quantum computing program in 2017. He works on a variety of topics in quantum computing architecture, from the simulation of materials and quantum devices to quantum software, algorithms and applications of quantum computers to quantum networking and quantum safe cryptography. His broader research interests span from high performance computing to the simulations of quantum devices and island ecosystems.
