About me

I'm a fourth-year PhD student at Harvard, advised by Anurag Anshu. Recently, I have been thinking about quantum complexity theory, quantum algorithms, and fault-tolerant computation. I am affiliated with the Harvard Quantum Initiative and the Theory of Computation group. My research is also supported by the IBM PhD Fellowship. Before, I obtained my bachelors degrees in physics and computer science from MIT in 2022.
