Travis Nicholson is a Principal Investigator at the Centre for Quantum Technologies and an Assistant Professor of Physics at NUS. He is an experimental physicist who uses ultracold atoms to study quantum optics, quantum metrology, and quantum many-body physics. He performed his PhD research at JILA in the United States. His PhD thesis demonstrated the world's most accurate atomic clock, which neither gains nor loses a second in 15 billion years. After this he was a postdoctoral fellow at MIT, studying nonlinear quantum optics with Rydberg atoms. Travis joined the CQT in 2017.
