I’m a third-year Ph.D. student at the University of Pennsylvania, co-advised by Prof. Gushu Li (Penn Quantum Systems Lab) and Prof. Anthony Sigillito (Penn Quantum Hardware Lab).

I earned B.S. in Electrical and Computer Engineering and minor in Computer Science from Carnegie Mellon University, during which I focused on digital logic design, computer architecture, and embedded systems.

Research

I design hardware and software for controlling and simulating spin qubits in semiconductor quantum dot devices, with an emphasis on deploying them in experiments.

Currently, I’m building a custom control architecture on RFSoC that is specially optimized for the control requirements of quantum dot spin qubits. Previously, I developed a machine-learning simulation framework that can simulate device tuning from cold start, mirroring real experimental workflows, and an accelerated virtual-gate extraction algorithm that reduces the number of measurement points needed.

I also developed much of our in-house experimental software, including:

• a high-performance measurement system that decouples all the software-incurred latencies using multi-process parallelism implemented on shared memory
• a quantum compiler that maps gates to pulses, which has achieved high single-qubit fidelity in experiments (>99.9%).
