Fig. 1: My group develops extreme-condition infrared-to-terahertz nanoscopy as a quantitative platform for probing collective and electronic excitations in quantum materials.

We focus on regimes where conventional optics fails: deep subwavelength confinement, cryogenic temperature, high magnetic field, and ultralow signal levels. By integrating synchrotron-based nano-IR, THz near-field microscopy, and bolometric superconducting detection, we aim to directly access a variety of quantum phenomena including quantum Hall and superconducting excitations beyond far-field observables. Our long-term goal is to establish nanoscale spectroscopy as a primary tool for quantum materials and quantum device characterization under extreme conditions
