__________
I am a finalyear PhD candidate at the University of Chicago, advised by Prof. Fred Chong. My research interests are in computer architectures, quantum computing, and error correction. I build systems that enable efficient compilation from highlevel circuits to nearterm quantum devices, and design techniques and algorithms to protect them against noise. I am a recipient of the William Rainey Harper Dissertation Fellowship, one of UChicago's highest honors, and the Siebel Scholarship.
In Spring and Summer 2020, I visited MIT under the IvyPlus Exchange Scholar Program. Before UChicago, I received my BS degrees in Computer Science and Physics from Carnegie Mellon University, where I was advised by Prof. Ryan O'Donnell.
