About

I am a senior research scientist at Amazon Web Services with a focus on quantum computing, optimization, and machine learning. I develop and analyze quantum algorithms, quantum solutions, and quantum error correcting codes that bridge theory and real-world hardware, striving to turn quantum advantage into practical solutions for real-world problems. Our open access book, "Quantum Algorithms: A Survey of Applications and End-to-end Complexities" was published by Cambridge University Press in April 2025.
