Molecular Ion Spectroscopy

We are pioneering new ultrasensitive and ultraprecise techniques to record ro-vibrational spectra of molecular ions in laboratory plasmas, with applications to fundamental molecular physics and the study of the interstellar medium.

Ball Plasmoid Spectroscopy

These unique, long-lived, water-based plasmoids are the best known analog of atmospheric ball lightning. We are using spectroscopic, chemical, and plasma diagnostic techniques to better understand the phenomena that sustain these plasmoids.
