Jiahui Liu

I am a third-year PhD student at UT Austin, working with Prof. Scott Aaronson and Prof. Brent Waters.
I'm generally interested in theoretical computer science, especially cryptography and quantum computing.

Education

Before coming to UT, I obtained my bachelor degree in computer science at Columbia University.
