Daniel Soh obtained his first PhD in high-power fiber lasers from the University of Southampton, UK. He then joined Calmar Laser Inc. and, later, JDS Uniphase to develop femtosecond fiber lasers and kilowatt continuous-wave high-power lasers, respectively. After that, he moved to Sandia National Laboratories in California, where he decided to get re-educated in quantum dynamic systems and quantum information science. Daniel obtained his second PhD in quantum dynamic systems from Stanford University. Since then, Daniel has been working on various quantum information science projects, including quantum nonlinear optics, quantum networks, quantum memory, and single-photon and single-phonon detectors using topological materials.
