Pat received his PhD in experimental physics from Darmstadt University of Technology in Germany, in 2007. He has worked at various research facilities over his career, including Leiden University, The Netherlands, the Institute for Solid State Physics at the University of Tokyo, the Low Temperature Laboratory at Kyoto University, Rutgers University, The Institute for Quantum Computing at the University of Waterloo in Canada, and the Department of Physics at Harvard University. His research focus has ranged from quantum fluids and solids, quantum sensing, including nitrogen vacancy defects in diamonds, and phosphorus defects in silicon, to experimental superconducting quantum computing - which he has been pursuing at IBM since 2016, where he is a team lead for quantum system integration and cryogenics.
