Combines optical microscopy, quantum sensing, and magnetic resonance to develop single-molecule and super-resolution microscopy methods, including orientation-resolved imaging and metrology, spanning biophysics and condensed matter applications.

Develops BioMEMS and nanopore-based biosensors, lab-on-chip devices, and micro/nano-fabricated platforms for pathogen and biomolecule detection and multiscale tissue engineering.

Develops novel optical biomedical imaging technologies (OCT, nonlinear/multiphoton microscopy) for cancer detection, primary-care diagnostics, and neurophotonics, and translates them toward clinical and commercial application.

Uses optical and magnetic tweezers to study single-molecule mechanics and dynamics of molecular motors and nucleic-acid-processing enzymes with piconewton force resolution.

Assembles optical-tweezer-trapped arrays of ultracold atoms and polar molecules (including NaRb) for quantum information science, quantum simulation, and cluster-state quantum computing, with associated Rydberg-based sensing capabilities.

Develops photonic-crystal-based optical biosensors and photonic-resonator-enhanced microscopy for digital-resolution, single-nanoparticle/single-quantum-dot biodetection, applied to protein, exosome, and nucleic acid diagnostics.

Observational exoplanet astronomer studying planetary system architectures and demographics using transit and radial-velocity surveys.

Works on quantum photonics and microwave-to-optical quantum transduction, collaborating on interconnects to link superconducting quantum processors via optical quantum networks.

Synthesizes and characterizes molecular magnets and metal-organic frameworks, using spectroscopy and electronic structure methods to design molecular spin qubits for quantum information science.

Develops balloon-borne and ground-based cosmic microwave background instrumentation (e.g., SPIDER, BICEP-family experiments) to search for inflationary gravitational-wave signatures.
