My group's research focuses on novel materials and devices to exploit interactions of light with matter:
  1. On-chip sensing and spectroscopy;
  2. Optical phase change materials and meta-optics;
  3. 2-D material photonic integration;
  4. Flexible photonics and polymer photonics;
  5. Optics for solar energy; and
  6. Magneto-optical isolation.
