Our research interests include tabletop tests for physics beyond the Standard Model, experimental gravitation, ultrasensitive force detection, and quantum optomechanics. Our research group moved to Northwestern in January 2018.

We study laser-cooling and trapping of dielectric nanoparticles for :
|
- ultra-precise force measurements
- testing gravity at the micron-scale
|
We are leading a collaborative experiment based on NMR in laser-polarized gases to search for the QCD Axion, a notable Dark Matter candidate.

- ARIADNE (Axion Resonant InterAction DetectioN Experiment)
|
We study interactions between laser-cooled atoms and micro-mechanical oscillators for :
|
- quantum opto-mechanics
- quantum information science
- studies of quantum behavior at macro-scales
