Hello! I'm a graduate student at MIT.

Research interests

I'm interested in quantum complexity theory and cryptography, and I mostly work on quantum proof (and argument) systems. Topics that interest me in complexity theory include MIP*, QMA(2) and quantum PCP. In cryptography, I've largely worked on quantum verification, and particularly on the application of MIP* techniques in single-prover settings. I'm currently advised by Anand Natarajan; I did my undergraduate degree at Caltech, and there I worked with Thomas Vidick and Chris Umans.

Miscellaneous

In case you're having a hard time placing my accent: I grew up in New Zealand. In my free time, I like to draw, to write, to play the violin, to sing, and to compose. I'm currently trying to learn Italian, though I haven't gotten too far yet. Some of my favourite things include Mozart's Don Giovanni, Dickens's Bleak House, Huxley's Brave New World, Austen's Mansfield Park, Sherlock Holmes, and the (semi-)animated film Allegro non troppo (directed by Bruno Bozzetto).
