My focus is on determining the fundamental laws physics via precision measurements. My main interests are in • searching for a possible fifth force, • testing the symmetries of the standard model, and • measuring properties of dark matter.
Currently I am working on experiments using quantum states with a large number of coherently polarized nuclear spins. By using such a macroscopic quantum state, very small perturbations to their behaviour can be detected. The current iteration under construction on the Tempe campus is designed to improve over existing experiments by 1000x. This will allow to us study new interactions at far greater sensitivity than before, and pave the way for future experiments at here-to-for unthinkable levels.
The central challenge of the experiment is intrinsically interesting: how to produce and control a quantum state with sufficiently high fidelity to be sure that any detected anomalies are due to violations of the laws of physics as we know them today. The practical work involves the use of cutting-edge quantum technologies like spin-exchange optical pumping and couping the nuclei into SQUIDs (superconducting quantum interference device).

We have several projects underway:
1. Build a system to optimally couple nuclear spins into a SQUID.
2. Develop quantum control algorithms to properly initialize the nuclear spin state
3. Demonstrate best-ever measurements of nuclear spin states
4. Search for ultra low mass dark matter
5. Perform an EDM measurement to CP-symmetry in the strong sector, and shed light on baryogenesis
6. Develop microfabricationn techniques specifically to improve precision measurements
