University of California, Berkeley, Berkeley, CA
Postdoctoral research hosted by Junqiao Wu
Highlight activities include:

• Achieved long-range optical interactions between epsilon-near-zero thin film materials and their analogy to superconducting proximity effect in electronic systems
• Demonstrated that near-zero-index materials can serve as a cladding layer for low-loss and geometry-invariant optical waveguides for miniaturized photonics
  These works are funded by the Miller research fellowship.

Northwestern University, Evanston, IL
Graduate research co-advised by Teri W. Odom and George C. Schatz
Highlight activities include:

• Achieved controlled multi-modal lasing from metal nanoparticle superlattices that enable access to multiple band-edge states in the photonic band structure
• Realized a mechanically tunable nanolaser based on metal nanoparticles on a flexible polymer matrix, as inspired by color changes of chameleons in nature
• Collaboratively demonstrated deterministic coupling of quantum emitters in hBN to plasmonic nanocavities for enhanced single-photon emission
• Collaboratively achieved continuous-wave nanoscale lasing at visible frequencies under near-infrared pumping with record-low power thresholds
• Established a robust computational approach in finite-difference time-domain methods to investigate time- and spatial- dependent lasing buildup in small photonic cavities
  These works resulted in 8 first-author publications in Nature Nanotechnology, Nature Materials, Nano Letters, ACS Photonics etc.
