I'm a Quantum Software Engineer at Infleqtion. I previously completed my PhD in Computer Science at the University of Chicago.

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.

Starting in August 2027 I'll be joining the University of Colorado Boulder as an Assistant Professor of Computer Science. I'll be actively recruiting PhD students during the upcoming application cycle, so if you would be interested in working together feel free to reach out!
