Jeff Champion
I am a PhD student in computer science at UT Austin working with David Wu. I'm generally interested in theoretical computer science, especially cryptography.
Previously, I majored in math and computer science at Northeastern University, where I was fortunate to be mentored by abhi shelat and Jonathan Ullman.
