CS PhD Student @ UChicago
QEC Consultant @ Infleqtion

I'm a final year Computer Science PhD student at the University of Chicago advised by Prof. Fred Chong. I previously completed my B.S. in Computer Science with a minor in Physics at Georgia Tech.

I'm focused on bridging the gap between current quantum devices and Fault-Tolerant Quantum Computing (FTQC). I have broad research interests within FTQC systems, including the co-design of Quantum Error Correction (QEC) with emerging quantum hardware, QEC decoding and other real-time systems for FTQC, and software solutions in FTQC research. Previously at Georgia Tech I worked on classical compilers, computer architecture, and robotics.
