I am a 2nd-year PhD student in the Computer Science Theory Group at Columbia University, co-advised by Tal Malkin and Henry Yuen. My research is at the intersection of cryptography and quantum computing, with an emphasis on quantum cryptography (not quite a tautology, I promise 🙂).

Previously I attended UT Austin, where I studied Computer Science and Mathematics with a Minor in Chinese, and worked as an undergraduate researcher with David Soloveichik on theoretical aspects of molecular and unconventional computing.

I enjoy learning languages, doing the NYT crossword and other puzzles (especially puzzle hunts), and skiing.

And yes, the url is not how my name is spelled. Sadly there were no .sky domains available for me, but I am an avid skier, so it feels like a decent fit :)
