MIT PhD Student in EECS

Massachusetts Institute of Technology

I am a fourth year PhD student in the MIT EECS Department advised by Professor Kevin O’Brien. My current research focuses on quantum measurement, gates, and control toward scalable error correction codes and fault-tolerant quantum computers. I am broadly interested in superconducting devices, circuits, and architectures that can enable foundational and scalable improvements in quantum processors.
