I am a Postdoctoral Scholar in Professor Oskar Painter's group at California Inistitute of Technology.
My research interest lies in nanophotonics, optomechanics, and quantum photonics. I am currently studying
nanoscale optomechanical systems for applications in integrated photonic devices and classical/quantum information processing.
1. Effective magnetic field for photons and topological photonic states [5,6,7,9,11,12,13,14] (theory and experiment).
My past research works include:
2. Magnetometry using nitrogen-vacancy centers in diamond  (experiment).
3. Magneto-optical effect in photonic crystals [3,4,10,15] (theory).
