My group uses atoms and molecules to develop new tools for precision measurements. Our current research projects involve optical atomic clocks and molecular ion spectroscopy.


  1. A compact external-cavity diode laser, using feedback from an optical fiber, Rev. Sci. Instr. (2017)
  2. Collisional frequency shift of a trapped-ion optical clock, Phys. Rev. A (2017)
  3. Broadband low-noise photodetector for Pound-Drever-Hall laser stabilization, Rev. Sci. Instr. (2016)
  4. Optical frequency standards for gravitational wave detection using satellite Doppler velocimetry, New. J. Phys. (2015)
