About

I am an assistant professor in the Department of Computer Science of the National University of Singapore. I earned my PhD from the University of Texas at Austin in 2021, where I was advised by Eric Price. After that, I was a senior member of technical staff at Sandia National Laboratories for four years, working with the Quantum Algorithms and Applications Collaboratory, before joining NUS in November 2025.

Note: I left Sandia on September 26 of 2025, so if you e-mailed my Sandia address after that date I am afraid I did not see your message.

Postdoc Hiring

I am looking to hire a research fellow (i.e. a postdoc) in quantum TCS. Potential areas of focus would include quantum space complexity, quantum property testing, or quantum communication complexity. Please feel free to e-mail me with any questions. The provisional deadline is April 1 2026. The posting can be found here.
