Research Interests

We aim to exploit fundamental light-material interactions and utilize them to design, fabricate and integrate novel photonic materials, structures, devices and systems for advanced optical neural interfaces.

Our recent works include:

  • Biocompatible and degradable waveguides for medical implants
  • Microscale LEDs and photodetectors for wireless optogenetic stimulation and fluorescence sensing
  • Optoelectronic upconversion devices for implantable light sources
