SCROLL TO EXPLORE ↓
01 / WHO I AM
Building interfaces
between light and sound.
I am a postdoctoral researcher at the University of California, Berkeley, working with Prof. Mengjie Yu.
My research spans the design, fabrication, and characterization of high-performance micro- and nanodevices across lithium niobate, silicon, and silicon nitride photonic platforms.
02 / WHAT I EXPLORE
Mechanical BICs
Engineering robust optomechanical resonators that suppress mechanical dissipation and remain tolerant to fabrication variations.
Light ↔ sound
Leveraging the piezoelectric and nonlinear properties of lithium niobate for optomechanical coupling, microwave-to-optical transduction, and quantum interfaces.
