I am a PhD Candidate in the Applied Science and Technology (AS&T) Program within the Department of EECS at UC Berkeley, conducting research under the supervision of Professor Kanté.
My current research lies at the intersection of Quantum Optics, Silicon Photonics, and Topological Photonics on engineering scalable single-photon sources for quantum information processing.
Before my doctoral study, I focused on wave-optics in the EUV and X-ray regimes for spectroscopy.
