Studies light-matter interaction at the nanoscale (metasurfaces, thermal emission, plasmonics) and, with Jennifer Choy, has developed metasurface polarizing beamsplitters that enable compact, chip-integrated atomic magnetometers (optically pumped magnetometry) alongside broader work in quantum and topological photonics.

Develops mass spectrometry-based imaging and proteomics technologies, including integration of tissue expansion microscopy with mass spectrometry imaging to achieve higher spatial resolution molecular maps of tissues such as tumors and brain.

Astroparticle physicist searching for sources of ultrahigh-energy cosmic particles with IceCube and developing next-generation astroparticle/neutrino detector instrumentation.

Studies galaxy formation and evolution using spectroscopic surveys of high-redshift galaxies with JWST and other facilities.

Studies the structure, kinematics, and dynamics of star clusters and star-forming regions, stellar binary populations, and alternative stellar-evolution pathways such as blue stragglers.

Develops cryogenic microcalorimeter/TES-based X-ray and far-infrared detector arrays used in X-ray astronomy and CMB instrumentation.

Observational astronomer studying the growth of supermassive black holes and their co-evolution with host galaxies.

Develops superconducting qubits and QND microwave single-photon detectors, applying them both to scalable quantum computing architectures and to axion/dark-photon dark-matter search experiments as ultra-sensitive quantum sensors.

Studies neutral-atom quantum computing and quantum optics with Rydberg atoms in optical tweezer arrays, including entanglement, nonlinear optics, and Rydberg-based electrometry/sensing.

Develops single-molecule genomics technologies using nanofluidics and optical mapping to analyze whole genomes and structural variation.
