Hogan proposed that the holographic principle implies a fundamental, universal quantum uncertainty ('holographic noise') in the transverse position of spacetime at the Planck scale, and co-led the Fermilab Holometer -- twin co-located, power-recycled Michelson interferometers -- to search for it, ruling out the simplest models to high significance. This is a distinct fundamental-light-physics/quantum-sensing approach from squeezed-light-enhanced GW interferometers (e.g., LIGO), using precision laser interferometry to probe quantum properties of spacetime itself rather than squeezing quantum noise in a detector.

Quantum information theorist with strong focus on quantum sensing. Directions: (1) error-correction-enhanced quantum sensing protocols surpassing Heisenberg limit; (2) quantum transduction theory for microwave-optical interfaces; (3) global-scale quantum network architecture; (4) room-temperature NV-based nanoscale magnetometry theory; (5) sub-wavelength quantum imaging protocols. Works closely with experimental quantum sensing groups at UChicago and beyond.

Kasthuri pioneered automated large-volume serial electron microscopy ('connectomics') to reconstruct complete synaptic wiring diagrams of the brain, and is now exploring synchrotron X-ray and photoemission electron microscopy (with the King lab) to remove imaging-speed bottlenecks and scale reconstructions toward whole-mouse and eventually human brains, comparing development, aging, and species differences. This is squarely the kind of resolution-pushing biological imaging the filter targets, achieving nanometer-scale synaptic resolution across cubic-millimeter-to-whole-brain volumes.

King develops polarization- and time-resolved PEEM together with ultrafast (scanning) transmission electron microscopy to image charge-carrier, exciton, and phonon dynamics with nanoscale (down to ~25 nm) spatial resolution at buried interfaces and in 2D materials such as black phosphorus. Her group is now retrofitting a high-throughput PEEM, in collaboration with the Kasthuri lab, for whole-brain connectomics -- an unpreferred/borderline inclusion since the core program is materials-science imaging rather than biosensing, but one that is directly extending resolution-pushing microscopy into neuroscience.

Klein pairs van der Waals heterostructure fabrication with a cryogenic scanning-probe 'Atomic Single Electron Transistor,' built on a quantum-twisting-microscope platform, to directly image sub-moire electrostatic potential landscapes with ultrasensitive, high-spatial-resolution electrometry. This is an unpreferred/borderline quantum-sensing inclusion: the sensor is an SET-based electrometer rather than an NV-ensemble magnetometer (which reaches pT/sqrt(Hz) via DEER/NMR/T1 protocols), but it shares the goal of pushing single-defect-level sensitivity for imaging quantum materials.

Experimental cosmologist developing next-generation CMB detector arrays. Directions: (1) CMB-S4 detector development — leading TES bolometer and MKID array design for 500,000-detector focal plane; (2) South Pole Telescope SPT-3G operations and analysis; (3) cryogenic readout electronics including SQUID multiplexing at millikelvin temperatures; (4) quantum-limited photon detection at mm/submm wavelengths. APS Fellow.

Best known as a collider (ATLAS) physicist, Miller also leads the BREAD collaboration's broadband dish-antenna search for axion dark matter, converting axions to photons inside a solenoid magnet and reading them out with a THz receiver and Fourier-transform spectrometer to cover mass ranges inaccessible to narrowband cavity haloscopes. This is a fundamentally different quantum-sensing strategy than solid-state NV-ensemble magnetometers/thermometers, which reach pT/sqrt(Hz)-class sensitivity via DEER, NMR, and T1-relaxometry protocols on spin ensembles; Miller's approach instead pushes broadband photon-counting sensitivity for fundamental-physics searches. Actively recruiting postdocs for BREAD instrumentation and analysis.
