Park's group works at the interface of physics, chemistry, and neuroscience, developing nanowire- and nanoelectrode-based intracellular electrophysiology probes as well as NV-diamond quantum sensing platforms (often in collaboration with Lukin), building on the same NV ensemble quantum-sensing lineage (DEER, nanoscale NMR, T1 relaxometry, pT/√Hz sensitivity) while also pushing nanoscale bioelectronic recording.

Pioneers living bioelectronics integrating semiconductor nanostructures with biological systems. Primary directions: (1) silicon nanowire / nanoporous silicon photoelectrochemical interfaces for optical neuromodulation with subcellular spatial resolution; (2) intracellular silicon nanowire probes for recording action potentials from individual organelles; (3) bioinspired flexible mesh electronics for in vivo neural and cardiac interfaces.
