Research

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.

I am involved in the EDMCubed and PolyEDM collaborations.

Designs

Code and hardware designs developed in my group are freely available at github.com/vuthalab.

Pythagon is an older Python blog that I update sporadically.
