Tom Purdy

  • Assistant Professor
210 Allen Hall


Dr. Purdy is interested in harnessing the quantum effects intrinsic in the mechanical interaction of light with macroscopic mechanical resonators to improve measurement and metrology. Previously, Dr. Purdy worked as a physicist in the Quantum Optics Group, Quantum Measurement Division, PML at NIST. Before joining NIST, Dr. Purdy has worked on a wide variety of optomechanical systems as a postdoctoral researcher at JILA and in his graduate work at UC Berkeley.
