Virginia Tech Work |

I'm growing a research group that specializes in quantum sensing at the
Virginia Tech National Security Institute
and the Bradley Department of Electrical and Computer Engineering.

P.U. Spin-off Work |

From Jan.~2018-Jan.~2024 I worked for a local start-up, Twinleaf LLC, mostly on a DARPA AMBIIENT grant, Atomic Magnetometer for Biological Imaging In Earth's Native Terrian (say that five times fast).
Some popular articles about this project are at Daily Mail and DARPA.
Our technique uses fast laser pulsing to optically pump Rb in Earth's field (0.5 G) with a goal of achieving 1 fT_{rms}/cm\sqrt{Hz} (currently at 10 fT_{rms}/cm\sqrt{Hz} in Phase 1). Our gradiometer uses a baseline of 3 cm, and aims to be
dead-zone and heading error free, for the purpose of in-the field magnetoencephalography (fancy speak for readin' brain waves).

Princeton Work |

In the Romalis group, I worked on a free-precession, dual noble-gas comagnetometer that is detected with an alkali magnetometer.
This device shows potential for use as a chip-scale reference NMR gyroscope, as well as searches for exotic spin couplings.
Our device has reached a precision sufficient to constrain spin-gravity searches at the 10 nHz level, and is accurate enough for detection of Earth's rotation without calibration.
This work is supported by DARPA and NSF grants.
DARPA BAA for C-SCAN NSF grant #1404325 View post on imgur.comA continuation of this work is being supported by an ONR grant, where 3He-21Ne cells are used. Initial testing shows that our 3He-21Ne cells are working well, with a 21Ne relaxation of roughly 2 hours. ONR BAA

Utah WorkIn the Saam group, I worked on hyperpolarizing noble gases with alkali metals, and did basic research in magnetic resonance under an NSF grant and a Swigart Foundation grant. In addition, I collaborated with the Boehme, Lupton, Raikh, and Vardeny groups at University of Utah, using magnetic resonance techniques to characterize organic semiconducting material under an NSF MRSEC grant.NSF grant #1121252 NSF grant #0855482 Utah |
